General Description

The MCP3421 is a single channel low-noise, high accuracy ΔΣ A/D converter with differential inputs and up to 18 bits of resolution in a small SOT-23-6 package.

The on-board precision 2.048V reference voltage enables an input range of ±2.048V differentially (Δ voltage = 4.096V).

The device uses a two-wire I2C compatible serial interface and operates from a single 2.7V to 5.5V power supply.
