产品概述

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 MCP3912 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 MCP3912 is capable of interfacing with a variety of voltage and current sensors, including shunts, current transformers, Rogowski coils and hall-effect sensors.
  • 93.5dB 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
  • Low power consumption (8.9mW at 3.3V, 5.6mW at 3.3V in low-power mode, typical)
