MCP3421 Datasheet (Microchip Technology) - 18-Bit Analog-to-Digital Converter

MCP3421, 18-Bit Analog-to-Digital Converter

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
