2 Channel Ultra-Precise Current Sensor

https://www.electronics-lab.com/project/2-channel-ultra-precise-current-sensor/

The project described here is a two-channel ultra-precise, current-sense amplifier that can measure voltage drops across shunt resistors over a wide common-mode range from 2.7 V to 120 V. The INA2290A1 chip is the heart of the project. The ultra-precise current measurement accuracy is achieved thanks to the combination of an ultra-low offset voltage of […]
