Isolated Analog and ADCs

The Si8921/22/3x/4x family of devices are designed to provide accurate isolated current and voltage measurement with very low drift across temperature. Based on Skyworks’ robust, third-generation isolation technology, the new family provides flexible voltage, current, output and package options to help developers reduce BOM cost and shrink board space for a wide range of industrial and green-energy applications including electric vehicle (EV) battery management and charging systems, dc-dc converters, and motor, solar and wind turbine inverters. The Si892x provides isolated current measurement with analog output, the Si893x provides isolated voltage measurement with both analog and DSM options, and the Si894x provides isolated current sensing with DSM output.
