Overview
Description
The RV1S9355A is an optically isolated delta-sigma modulator that includes a high-accuracy A/D converter with 20MHz internal clock and converts an analog voltage input into one-bit data stream. The RV1S9355A provides an Effective Number of Bits (ENOB) of 14 bits (TYP.) with a Sinc3 digital filter. The RV1S9355A is designed specifically for high common mode transient immunity (CMTI), high SNR, and high linearity (low nonlinearity). The RV1S9355A is suitable for motor current sensing in industrial instruments and enables high-precision measurement in a harsh noise environment.
Features
