10μA-10mA Low-Side Current Sensor
https://www.electronics-lab.com/project/10%ce%bca-10ma-low-side-current-sensor/
This single-supply, low-side, current-sensing solution accurately detects load current between 10μΑ and 10mA. A unique yet simple gain-switching network was implemented to measure the three-decade load current range accurately. The linear range of the output is from 100mV to 4.90V. INA326 instrumentation amplifier is used since low-side sensing is desirable because the common-mode voltage is […]
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 […]
0-1A Single-Supply, Low-Side, Current Sensor with Output 0 to 4.9V
https://www.electronics-lab.com/project/0-1a-single-supply-low-side-current-sensor-output-0-to-4-9v/
This single-supply, low-side, current sensing solution accurately detects load current between 0 and 1A. The current sensor measures 0 to 1A across the shunt resistor, providing 0 to 4.9V output. The OPA320 features wide bandwidth and low offset voltage making it an excellent amplifier for this design. With a single 5V supply, the LM7705 negative […]
