A/D-Wandler, 24-bit, 4-Kanal, SSOP-28

The MCP3912 is a 3V four channel Analog-Front-End (AFE) containing four synchronous sampling Delta-Sigma Analog-to-Digital Converters (ADC), four PGAs, phase delay compensation block, internal voltage reference, digital offset and gain error calibration registers and high-speed 20 MHz SPI compatible serial interface. The MCP3912 AFE is capable of interfacing to a variety of voltage and current sensors including shunts, current transformers, Rogowski coils and Hall effect sensors
