MCP 3919A1-E/SS

The MCP3919 is a 3 V three channel Analog-Front-End (AFE) containing four synchronous sampling Delta-Sigma Analog-to-Digital Converters (ADC), three PGAs, phase delay compensation block, internal voltage reference, digital offset and gain error calibration registers and high-speed 20 MHz SPI compatible serial interface. A 2-wire serial interface mode greatly reduces system cost by requring only a single bidirectional isolator per phase. The MCP3919 AFE is capable of interfacing to a variety of voltage and current sensors including shunts, current transformers, Rogowski coils and Hall effect sensors
