SI8902 ISOLATED MONITORING ADC

 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 s.
