Overview

The MCP3912A1-E/SS is a 4-channel Analog Front End (AFE) containing four synchronous sampling delta-sigma, analog-to-digital converters (ADC), four PGAs, phase delay compensation block, low-drift internal voltage reference, digital offset and gain error calibration registers and high-speed 20MHz SPI-compatible serial interface. The MCP3912A1-E/SS ADCs are fully configurable, with features such as 16/24-bit resolution, Oversampling Ratio (OSR) from 32 to 4096, gain from 1x to 32x, independent Shutdown and Reset, dithering and autozeroing. It also includes a register-map lock through an 8-bit secure key to stop unwanted write commands from processing. The MCP3912A1-E/SS is capable of interfacing with a variety of voltage and current sensors, including shunts, current transformers, Rogowski coils and hall-effect sensors.
