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
