LT6658 – Precision Dual Output, High Current, Low Noise, Voltage Reference
https://www.electronics-lab.com/lt6658-precision-dual-output-high-current-low-noise-voltage-reference/
Linear Technology announces the LT6658, a precision voltage reference that incorporates two high current output buffers. The LT®6658 precision 2.5V dual output reference combines the performance of a low drift low noise reference and a linear regulator. Both outputs are ideal for driving the precision reference inputs of high resolution ADCs and DACs, even with […]
Capacitor self-diagnostics
https://www.electronics-lab.com/capacitor-self-diagnostics/
Peter Demchenko discuss about a design idea on how to test capacitors in circuit. The electrolytic capacitor is far from being the most reliable electronic component. One of its failure modes – a gradual loss of capacity – can hardly be noticed until power supply malfunction occurs. Thus, any chance to monitor the condition of […]

Designed for everyday food analytics, the SFH 4735 LED emits broadband infrared light in a wavelength range from 650 to 1,050 nanometers. by Julien Happich @ edn-europe.com The component is well suited as a light source for near-infrared spectroscopy, for example to assess the quality of food thanks to mini spectrometers that could be developed […]
Temperature Measurement with NTC Thermistors
https://www.electronics-lab.com/temperature-measurement-ntc-thermistors/
Philip Kane @ jameco.com discuss about how to measure temperature with NTC thermistors. He writes: Thermistors (thermal resistors) are temperature dependent variable resistors. There are two types of thermistors, Positive Temperature Coefficient (PTC) and Negative Temperature Coefficient (NTC). When the temperature increases, PTC thermistor resistance will increase and NTC thermistor resistance will decrease. They exhibit […]
