MCP3901 Data Sheet

http://www.microchip.com/stellent/images/mchpsiteimages/dwnfolder.gifMCP3901 Data Sheet - Two Channel Analog Front End


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.
