MCP 3912A1-E/SS

The MCP3912 is a 3-V four-channel analogue front end (AFE) containing four synchronous sampling delta-sigma analogue-to-digital converters (ADC), four PGAs, phase delay compensation block, internal voltage reference, digital offset and gain error calibration registers and a high-speed 20-MHz SPI compatible serial interface. The MCP3912 AFE can interface with a variety of voltage and current sensors, including shunts, current transformers, Rogowski coils and Hall effect sensors.

• Four synchronous sampling 24-bit delta-sigma A/D converters
• 93.5 dB SINAD, -107 dBc THD, 112 dBFS SFDR
• Enables 0.1% typical active power measurement error over a 10,000:1 dynamic range
• 2.7 - 3.6 V AVDD, DVDD
• Programmable data rate up to 125 ksps
• Oversampling ratio up to 4096
• Ultra low-power shutdown mode with < 10 µA
• -122 dB crosstalk between the two channels
• Low drift 1.2-V internal voltage reference: 9 ppm/°C
• Differential voltage reference input pins
• High gain PGA on each channel (up to 32 V/V)
• Phase delay compensation with 1-µs time resolution
