MCP3901

In Production

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.We welcome questions, comments and recommendations for improvements to this page - please contact us at: ADCwebrequests@microchip.com if you have any; please mention the part number in the email subject header....
