MCP3421 I2C SOT23-6 18-Bit Analog-to-Digital Converter A/D Converter ADC Evaluation Module Board For PICkit Serial Analyzer Module
The MCP3421 is a single channel low-noise, high accuracy 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
The device uses a two-wire I2C compatible serial interface and operates from a single 2.7V to 5.5V power supply.
