Si8902 Datasheet Isolated Monitoring Adc

Manufacturer: Skyworks Solutions

Overview: Si8900/1/2 ISOLATED MONITORING ADC.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

 Isolated temp/humidity sensing  Switch mode power systems  Telemetry The Si8900/1/2 series of isolated monitoring ADCs are useful as linear signal galvanic isolators, level shifters, and/or ground loop eliminators in many applications including power-delivery systems and solar inverters.

These devices integrate a 10-bit SAR ADC subsystem, supervisory state machine and isolated UART (Si8900), I2C/SMbus port (Si8901), or SPI Port (Si8902) in a single package.

Based on proprietary CMOS isolation technology, ordering options include a choice of 2.5 or 5 kV isolation ratings.
