Product Overview

The MCP3914A1-E/MV is an 8-channel Analog Front End (AFE), containing eight synchronous sampling delta-sigma, analog-to-digital converters (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. The MCP3914 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. The MCP3914 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. The MCP3914 is capable of interfacing with a variety of voltage and current sensors, including shunts, current transformers, Rogowski coils and hall-effect sensors.
  • 94.5dB SINAD, -107dBc Total harmonic distortion (THD) (up to 35th harmonic)
  • 112dBFS SFDR for each channel
  • Enables 0.1% typical active power measurement error over a 10,000:1 dynamic range
  • 16-bit Cyclic redundancy check (CRC) checksum on all communications for secure data transfers
  • 16-bit CRC checksum and interrupt alert for register map configuration
  • Register map lock with 8-bit secure key
  • Programmable data rate up to 125ksps
  • 4MHz Maximum sampling frequency, 16MHz Maximum master clock
  • Ultra low-power shutdown mode with <10µA
  • -122dB Crosstalk between the two channels
  • 9ppm/°C Low drift 1.2V internal voltage reference
  • Differential voltage reference input pins
  • High gain PGA on each channel (up to 32V/V)
  • Phase delay compensation with 1µs time resolution
  • Separate data ready pin for easy synchronization
  • Individual 24-bit Digital offset and gain error correction for each channel
  • High-speed 20MHz SPI Interface with mode 0,0 and 1,1 compatibility
  • Continuous read/write modes for minimum communication
