Description18-Bit Low-Noise I2C ADC, Differential Input, On-Board Reference, SOT-23-6 Package

Product Overview

The MCP3421A0T-E/CH is a high-precision, ultra-low-noise 18-bit sigma-delta analog-to-digital converter with a built-in precision voltage reference and I2C digital interface. It supports differential analog input, programmable gain amplifier (PGA), and selectable resolution modes, delivering high accuracy for low-level sensor signals. The device operates from a single 2.7V to 5.5V supply, features low power consumption, and provides continuous conversion with high linearity and stability. Designed for compact, battery-powered, and noise-sensitive applications, it offers reliable performance in industrial, medical, and portable measurement systems. Housed in a tiny SOT-23-6 package, it enables minimal PCB footprint and high-density integration.
