AMC131M03QDFMRQ1 TI Isolated ADC | 20-SOIC | 3-Ch, 16-bit, 1.5kVrms

Product Overview

The AMC131M03QDFMRQ1 is a high-performance, isolated delta-sigma (ΔΣ) modulator from Texas Instruments, designed for precise current and voltage sensing in automotive and industrial applications. This device integrates three independent, 16-bit resolution channels with a maximum data rate of 21.3 kSPS per channel. It features reinforced isolation up to 1.5 kVrms (working voltage) and 3.5 kVrms (peak transient), ensuring robust signal integrity in noisy environments. The device operates from a single 3.3V supply and includes an internal reference, making it ideal for space-constrained designs. Housed in a 20-pin SOIC package, it supports both SPI and daisy-chain interfaces for easy integration with microcontrollers.
