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.
The very low signal delay of the Si8920 allows control systems to respond quickly to fault conditions or changes in load. Low offset and gain drift ensure that accuracy is maintained over the entire operating temperature range. Exceptionally high commonmode transient immunity means that the Si8920 delivers accurate measurements even in the presence of high-power switching as is found in motor drive systems and inverters.
