SI8920BC-ISR Galvanically Isolated Amplifier IC with Low Voltage Differential Input for Current Shunt Measurement

The Si8920 is a galvanically isolated analog amplifier. The low-voltage differential input is ideal for measuring voltage across a current shunt resistor or for any place where a sensor must be isolated from the control system. The output is a differential analog signal amplified by either 8.1x or 16.2x.
