The MCP3919 is a 3V three channel Analog-Front-End (AFE) containing three simultaneous 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?requiring 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\n类似型号MCP3919A1-E/SS, MCP3919A1-E/MQ, MCP3919A1T-E/MQ
