This autofocus camera is tiny, but definitely not to be underestimated: The uEye XS from IDS Imaging Development Systems weighs just 12 grams and fits into almost any application with its size of just 26.4 x 23 x 21.7 mm. Thanks to its autofocus and 5 MP CMOS sensor, it delivers consistently sharp images and videos from a distance of just 10 cm – for example in hand-held scanners, on robotic arms or in passport photo machines. The uEye XS starter set is ideal for testing the camera. In addition to the compact USB2 camera, it includes a cable, a tripod adapter and a tripod.
If the distance between the lens and the object is constantly changing, users benefit from industrial cameras with automatic focus. They eliminate the need for manual refocusing and ensure that objects or labels are always perfectly visible. When it comes to image quality, however, other factors are also decisive, such as natural color reproduction and harmonious contrast.
IDS has therefore equipped the uEye XS with many other practical automatic features familiar from consumer technology. This includes white balance, exposure, and gain. As a result, it delivers the best possible result in every situation. Anyone wishing to fine-tune even more precisely can adjust settings in the SDK (IDS Software Suite).
Thanks to its small size and the proven USB2 interface, the uEyeXS camera is suitable as a component in embedded vision systems. It is used, for example, in medical or security applications, in transport and logistics or in kiosk systems.

This high-speed, isolated Undervoltage and Overvoltage detection project is implemented with a dual isolated window comparator with an adjustable threshold (AMC23C14). This circuit is designed for industrial field-supply applications where the controller side must detect whether the remote module supply voltage is in a valid range.
The AMC23C14 has open-drain outputs that are pulled up to VCC, and are driven low when the input voltage exceeds the threshold voltage of each comparator. In these measurements, OUT1 (trace 3) transitions low if Vsupply exceeds 28.8V, and OUT2 transitions low if Vsupply exceeds 20.8V. Component variations and the comparator hysteresis can affect the trip thresholds, but in this case, the trip point is within less than 1% of the desired values. The voltage thresholds vary slightly if Vsupply is rising or falling. The second waveform depicts this with OUT1 triggering at 28.6V instead of 28.8V.
U1 (CRE1S0505SC) is an isolated DC-DC converter that provides 5V to the input side circuitry. The module can be powered from input side power, using R1 1K SMD size 0805 and Zener diode 27V 1W SMD. Do not install U1 in this case, the output side requires separate 2.7V to 5.5V VCC.
Over Current and Short Circuit Application
The project is designed for Under/Over voltage detection. However, the project also has provisions to be used for over-current and short-circuit detection. Read the datasheet of the chip for more info. Do not install R3, R6, and R7, Install R10 = 10mOhms SMD size 2512, solder jumper J1 under the PCB. This configuration will help you to detect over current and short circuit across the shunt resistor R10.

The AMC23C14 is a dual, isolated window comparator with a short response time. The open-drain outputs are separated from the input circuitry by an isolation barrier that is highly resistant to magnetic interference. This barrier is certified to provide reinforced galvanic isolation of up to 5 kVRMS according to VDE 0884-17 and UL1577, and supports a working voltage of up to 1 kVPK.
Both comparators have windows that are centred around 0 V, meaning that the comparators trip if the input exceeds the thresholds in a positive or negative direction. One comparator has fixed thresholds of ±300 mV. The second comparator has adjustable thresholds from ±20 mV to ±300 mV through a single external resistor.
The AMC23C14 also supports a positive-comparator only mode. When the voltage on the REF pin is greater than 550 mV, the negative comparators are disabled and only the positive comparators are functional. The reference voltage in this mode can be as high as 2.7 V. This mode is particularly useful for monitoring positive voltage supplies.
This is a simple Proportional, Integral (PI) temperature control amplifier. A complete thermoelectric cooler (TEC) controller can be created using this PI amplifier and OPA569 Power Op-Amp or other output amplifiers such as DRV591, DRV592 and DRV593. Proportional-integrator compensation is simpler to adjust and often provides an adequate thermal transient response to the TEC driver amplifiers. The project consists INA330 chip and OPA2340 OPAMP. The INA330 provides thermistor excitation and generates an output voltage proportional to the difference in resistances applied to the inputs. OPA2340 is used to create the PI closed Loop.
The board is based on application note Figure 8 from the datasheet of INA330. Please Refer to the datasheet of INA330 to learn more about the project and applications.
U1 LM385-1.2V generates the reference voltage 1.23V, and REF3012 SOT23-2 U4 chip can be used as an alternative to U1. PI loop compensation can be optimized for loop stability and best response to thermal transients by adjusting R4, R11, C8, and C9. To facilitate the optimization of loop dynamics, the value of these components is important and will depend on the Thermal behavior of the TEC.

INA330 uses only one precision resistor R2 plus the thermistor RT1, thus providing an alternative to the traditional bridge circuit. The circuit maintains excellent accuracy for temperature control applications. An excitation voltage is applied to the thermistor (RTHERM) RT1 and precision resistor (RSET) R2, creating currents I1 and I2. The current conveyor circuit produces an output current, I0, equal to I1 – I2, which flows through the external gain-setting resistor. A buffered voltage output proportional to I0 is also provided. The loop controls temperature to an adjustable set-point of 22.5°C to 27.5°C. The nominal 10kΩ at 25°C thermistor ranges from approximately 11.4kΩ to 8.7kΩ over this range. A 1.23V excitation voltage is applied to V1 and V2, producing a nominal 100µA current in the 10kΩ RSET resistor. The thermistor current is approximately 100µA at 25°C, but will vary above or below this value over the ±2.5°C set-point temperature range. The difference of these two currents flows in the gain-set resistor, RG. This produces a voltage output of approximately 0.9V/°C. The set-point temperature is adjusted with VADJ. Thus, the voltage at VO is the sum of (IO)(RG) + VADJ. VADJ can be manually adjusted or set with a Digital-to-Analog (D/A) converter. Optionally, Thus, the feedback loop will drive the heating or cooling of the TEC to force VO to equal VBIAS. VADJ = 2.5V will produce a set-point temperature of 25°C. VADJ = 2.5V + 0.9V will change the set-point by 1°C. A 0V to 5V D/A converter will provide approximately ±2.5°C adjustment range. A 12-bit D/A converter will allow for approximately 0.001°C resolution on the set-point temperature. For best temperature stability, the set-point temperature voltage should be derived ratiometrically from VBIAS. A D/A converter used to derive the set-point voltage should share the same reference voltage source as VBIAS. Likewise.

This design is intended to translate a small unipolar signal to a wide bipolar signal. A common application is to translate a 0 to 5V DAC output to a ±10V bipolar signal. All resistors are 1% but it is advisable to select 0.1% 20 ppm/°C resistors for good gain, offset accuracy, and drift tolerance. A calibration at room temperature can be done to minimize the gain error, but gain drift can only be reduced by minimizing the resistor drift (choosing resistors with TC ≤ 20 ppm/°C). The project is built using OPA2206 Precision, bipolar, e‑trim OPAMP. REF5050 provides 5V reference voltage to OPAMP. The board works with a dual ±15V DC Power Supply.

This is an advanced Motion module providing a fully featured, high-performance inverter output stage for AC induction, BLDC and PMSM motors such as refrigerators, fans, and pumps. This module is based on NFA50460 chip which integrates the optimized gate drive of the built−in IGBTs (FS4 RC IGBT technology) to minimize EMI and losses, while also providing multiple on−module protection features including under−voltage lockouts and thermal monitoring. The built−in high-speed Driver IC requires only a single supply voltage and translates the incoming logic−level gate inputs to the high voltage, high current drive signals required to properly drive the module’s internal IGBTs. Separate open emitter IGBT terminals are available for each phase to support the widest variety of control algorithms. Heatsink is a must for the IC before conducting any test.

Comparator U2B is provided for over temperature, the output of U2B is high when IPM temperature is below 80 degrees C and goes low when the temperature reaches the threshold. A heatsink is a must for full load current, 2 mounting holes are provided throughout the PCB to mount the heatsink as shown in Figure below. Silicone thermal compound, also called thermal grease, should be applied between the heat sink and the flat surface of the IPM to fill microscopic air gaps due to imperfect flatness that ultimately reduces the contact thermal resistance.

The project presented here is a Voltage Controlled Amplifier (VCA). A VCA board helps users control the Audio Level from a remote potentiometer. It requires a single-ended audio signal in the input. Gain control voltage can be adjusted through an on-board potentiometer or use an external potentiometer connected to CN4. The project works with a dual ±15V power supply. Screw terminal connectors are provided for signal input and signal output. The project is built using THAT2181LA chip, a VCA that is designed for high-performance audio-frequency applications requiring exponential gain control, low distortion, wide dynamic range, and low control-voltage feedthrough. These parts control gain by converting an input current signal to a bipolar logged voltage, adding a DC control voltage, and re-converting the summed voltage back to a current through a bipolar antilog circuit. Stereo control of VCA with a single potentiometer is possible.
THAT 2181-series trimmable Blackmer voltage-controlled amplifier (VCAs) ICs are very high-performance current-in/current-out devices with two opposing-polarity, voltage-sensitive control ports. They offer wide-range exponential control of gain and attenuation with low signal distortion.
Trimming
The trim should be adjusted for minimum harmonic distortion using PR1. This is usually done by applying a middle-level, middle-frequency signal (e.g. 1 kHz at 1 V) to the audio input, setting the VCA to 0 dB gain, and adjusting the SYM trim while observing THD at the output. In THAT2181LA, this adjustment coincides closely with the setting which produces minimum control-voltage feedthrough, though the two settings are not always identical.
This mini-module helps users to measure the RMS noise of AC signal. Apply the AC noise signal to the input and the circuit outputs a DC voltage. Signal bandwidth is 1Khz to 100Khz and input sensitivity is 1 μVolt RMS. The LT6203 ultra-low noise, low power op-amp amplifies the low-level signal. Further, this signal is converted into a DC voltage by LTC1966 True RMS converter chip from Analog Devices. The circuit works with dual supply +/-5V DC and consumes very low current.
VOutput = 1mVDC/1μVolt RMS Noise
