The Si8921 and Si8922 galvanically isolated analog amplifiers feature low-voltage differential input, ideal for measuring voltage across a current shunt resistor or any place where a sensor must be isolated 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 Si8921/22 allows .
• Low-voltage differential input: ±62.5 mV and ±250 mV options
• Low signal delay: 0.8 µs
• Typical input offset: ±0.40 µV
• Typical gain error: ±0.06%
• Excellent drift specifications
- 0.5 µV/°C offset drift -
–9 ppm/°C typical gain drift
• 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
• Automotive-grade OPNs available - AEC-Q100 qualification - AIAG-compliant PPAP documentation support - IMDS and CAMDS listing support
• Compact packages - 8-pin wide body stretched SOIC - 8-pin narrow .
