Overview

The MCP3421A3T-E/CH ADC can be used for various high accuracyanalog-to-digital data conversion applications where ease of use, lowpower consumption and small footprint are major considerations.TheMCP3421A3T-E/CH is a single channel low-noise, high accuracy delta-sigma A/Dconverter with differential inputs and up to 18 bits of resolution in asmall SOT-23-6 package.Please consider the MCP3425 version forresolutions up to 16 bits. The on-board precision 2.048V referencevoltage enables a differential input range of ±2.048V.The device uses atwo-wire I2C™ compatible interface and operates from asingle power supply ranging from 2.7V to 5.5V.The MCP3421A3T-E/CH ADC performs conversions at rates of 3.75, 15, 60 or 240samples per second with corresponding resolutions of 18, 16, 14 and 12 bits.The onboard programmable gain amplifier (PGA) provides gain up to 8x.The device has two conversion modes: Continuous mode and One-Shot mode.In One-Shot mode, the device enters a low current standby modeautomatically after a conversion, greatly reducing power use.
