Original POWER ISOLATION SI8921BD-IS4R

The SI8921BD-IS4R is a high-precision isolated amplifier from Silicon Labs designed for industrial servo applications. It excels in motor phase current sensing within inverters, offering accurate differential amplification of signals obtained across shunt resistors in the circuit. With an 8.2x gain and a gain error margin of ±0.3%, this device ensures reliable signal isolation and conditioning. The 'R' variant possibly denotes a specific package or configuration option, making it suitable for robust and noise-immune voltage or current sampling in demanding environments.
