Programmable Bridge Resistive Sensor Signal Conditioner
https://www.electronics-lab.com/project/programmable-bridge-resistive-sensor-signal-conditioner/
The module presented here is a sensor signal conditioner based on ZSC31010 CMOS integrated circuit, which enables easy and precise calibration of resistive bridge sensors via EEPROM programming. When mated to a resistive bridge sensor, it will digitally calibrate offset and gain with the option to calibrate offset and gain coefficients and linearity over temperature. […]
DC Electronic Load – 1A
https://www.electronics-lab.com/project/dc-electronic-load-1a/
This is a very precise Electronic Load project built using the ultra-Precision, Low-Noise OPAMP MAX44251 from Analog Devices. The project can sink current from a power source. It can be used as test gear for power supplies, chargers, solar panels, batteries, and DC-DC converters. The resistor R11 acts as a shunt, OPAMPs convert current into […]
Dual Output Adjustable Linear Power Supply +/-1.2V to +/-12V @ 250mA
https://www.electronics-lab.com/project/dual-output-adjustable-linear-power-supply-1-2v-to-12v-250ma/
This project is a solution to power up most devices or projects requiring dual (+/-) adjustable power. The circuit consists of a stepdown transformer, bridge rectifier, DC filter capacitors, LM317 positive and LM337 negative adjustable voltage regulators, 2 x trimmer pot for independent output voltage adjust, and power LEDs. Parts Explanation Connector CN1 : 230V/115V […]
15V to 60V – Three-Phase Brushless DC Motor Pre-Driver
https://www.electronics-lab.com/project/15v-to-60v-three-phase-brushless-dc-motor-pre-driver/
The project presented here is a three-phase BLDC motor pre-driver. The project consists of 3x half-bridge IR2101 driver IC and 6 channel high current N-MOSFETS. The project can be configured as 3 independent half-bridges H-bridge for a brushed DC motor, or a single high current brushless motor driver. The rotor position can be detected using […]
