Si8935 Datasheet Delta-sigma Modulator

Manufacturer: Skyworks Solutions

Overview: DATA SHEET Si8935/36/37 Delta-Sigma Modulator for Voltage Measurement Applications • Industrial, HEV and renewable energy inverters • AC, brushless, and DC motor controls and drives • Variable speed motor control in.

General Description

The Si8935/36/37 are galvanically isolated delta-sigma modulators optimized for voltage sensing.

Its 2.5 V input range is ideal for isolated voltage sensing applications.

The Si8935/ 36/37 provides excellent linearity with low offset and gain drift to ensure that accuracy is maintained over the entire operating temperature range.

Key Features
