Si8931 - Isolated Analog Amplifier

Datasheet Summary

Description

The Si8931 and Si8932 galvanically isolated analog amplifiers feature 2.5 V input range and are optimized for isolated voltage sensing applications.

The output is a differential analog signal (Si8931) or a single-ended signal (Si8932) proportional to the input voltage.

Features

  • 0 to 2.5 V nominal input voltage.
  • Low signal delay: 1 µs.
  • Typical input offset: 0.16 mV.
  • Typical gain error: ±0.06%.
  • Excellent drift specifications - 0.75 µV/°C offset drift - 6 ppm/°C typical gain drift.
  • Typical nonlinearity: 0.01%.
  • Typical SNR: 76 dB.
  • High common-mode transient immunity: 75 kV/µs.
  • Automotive-grade OPNs available - AEC-Q100 qualification - AIAG-compliant PPAP documentation support - IMDS and CAMDS.
