Microchip MCP3913A1-E/SSVAO

MCP3913A1-E/SSVAO 概要

The MCP3913 device is a 3V six-channel Analog Front End (AFE, containing six simultaneous sampling delta-sigma ADCs, six PGAs, phase delay compensation block, low-drift internal voltage reference, digital offset and gain errorcalibration registers, and high-speed 20 MHz SPI compatible serial interface.The MCP3913 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 auto-zeroing.The MCP3913 AFE includes advanced security features to secure the communications and the configuration settings, such as a CRC-16 checksum on both serial data outputs and static register map configuration. It also includes a register-map lock through an 8-bit secure key to stop unwanted write commands from processing.The MCP3913 AFE is capable of interfacing with a variety of voltage and current sensors, including shunts, current transformers, Rogowski coils and Hall-effect sensors.
