Si8920 Overview
Si8920 Data Sheet Isolated Amplifier 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.
