SI8921AD-IS4 Description


The SI8921AD-IS4 is a galvanically isolated analog amplifier. The low-voltage differential input is ideal for measuring the voltage across a current shunt resistor or where a sensor must be separated from the control system. The output is a differential analog signal amplified by either 8.2x or 32.8x. The very low signal delay of the SI8921AD-IS4 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. 



SI8921AD-IS4 Features


Low-voltage differential input:

±62.5 mV and ±250 mV options

Low signal delay: 0.8 µs

Typical input offset: ±40 µV

Typical gain error: ±0.06%

Typical Nonlinearity: 0.003% full scale

Typical SNR: 82 dB over 100 kHz bandwidth

Typical THD: –88 dB

High common-mode transient immunity: 75 kV/µs



SI8921AD-IS4 Applications


Industrial, HEV, and renewable energy inverters

AC, Brushless, and DC motor controls and drives

Variable speed motor control in white consumer goods

Isolated switch mode and UPS power supplies

Automotive on-board chargers, battery management systems, and charging stations
