MCP3903
For product comparison, please consider:
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- Six simultaneously sampled 16/24-bit resolution delta-sigma A/D converters
- 91 dB SINAD, -100 dBc THD, 102 dB SFDR
- Programmable data rate up to 64 ksps
- Internal voltage reference with low drift of 5 ppm/°C
- Internal PGAs on each channel with gain of 32 V/V
- Phase delay compensation between channels with 1 µs resolution
- Extended Temperature Range: -40°C to +125°C
