MCP3914A1-E/MV

MCP3914A1-E/MV is an eight-channel analogue front-end containing eight synchronous sampling DeltaSigma analogue-to-digital converter (ADC), eight 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. It 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. It 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. Application includes polyphase energy meters, energy metering and power measurement, automotive, portable instrumentation, medical and power monitoring, audio/voice recognition.
