MCP3901

For product comparison, please consider:

The MCP3901 dual channel analog front end features high accuracy 16/24-bit delta-sigma A/D converters, internal programmable gain amplifiers, an internal voltage reference, and phase-delay compensation with up to 91 dB SINAD. Communication with the MCP3901 is done via the SPI interface enabling control of the PGAs, oversampling ratio for control of the output data rate (up to 64 ksps), resolution, dithering, shutdown and other communication features.

Features
  • Two simultaneously sampled 16/24-bit resolution delta-sigma A/D converters
  • 91 dB SINAD, -104 dBc THD, 109 dB SFDR
  • Programmable data rate up to 64 ksps
  • Internal voltage reference with low drift of 12 ppm/°C
  • Internal PGAs on each channel with gain of 32 V/V
  • Phase delay compensation between channels with 1 µs resolution
  • Low power consumption (14mW at 5V)
  • Extended Temperature Range: -40°C to +125°C
