Microchip MCP3421A0T-E/CH MCP3421A0T-E/CH Analogue to Digital Converter 18 bit 3.75 SPS Differential Single Ended I2C 2.7 V

The MCP3421A0T-E/CH is a 1-channel low-noise high accuracy delta-sigma Analogue-to-Digital Converter with differential inputs and up to 18-bit of resolution. 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 power supply ranging from 2.7 to 5.5V. The MCP3421 device performs conversions at rates of 3.75, 15, 60 or 240 samples per second depending on user controllable configuration bit settings using the two-wire I²C� compatible serial interface. This device has an onboard programmable gain amplifier (PGA). User can select the PGA gain of x1, x2, x4 or x8 before the analogue-to-digital conversion takes place. This allows the MCP3421 device to convert a smaller input signal with high resolution. The device has two conversion continuous and one-shot modes.
