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.
The MCP3903 ADC Evaluation Board for 16-bit MCU system provides the ability to evaluate the performance of the MCP3903 six channel sigma-delta ADC. It also provides a development platform for 16-bit PIC-based applications, using existing 100-pin PIM systems.
Devices Supported: MCP3903, PIC24F, PIC24H, dsPIC33, MCP2200
