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 […]
