Si8900/1/2 I SOLATED M ONITORING ADC Features Applications Description 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 Silicon Labs’ proprietary CMOS isolation technology, ordering options include a choice of 2.5 or 5 kV isolation ratings. All products are safety certified by UL, CSA, and VDE (pending). The Si8900/1/2 devices offer a typical common-mode transient immunity performance of 45 kV/µs for robust performance in noisy and high-voltage environments. Devices in this family are available in 16-pin SOIC wide-body packages.
