View Side By Side Comparison

The MCP3903 six channel analog front end, ideal for three phase energy measurement, power monitoring, and other applications requiring multiple high accuracy ADCs. The MCP3903 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 MCP3903 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
