Device Overview

Summary

The MCP3910 is a 3V dual channel Analog-Front-End (AFE) containing two synchronous sampling Delta-Sigma Analog-to-Digital Converters (ADC), two PGAs, phase delay compensation block, internal voltage reference, modulator output block, and high speed 20 MHz SPI compatible serial interface. For poly-phase shunt based energy meters, the MCP3910 2-wire serial interface greatly reduces system cost by requiring only a single bidirectional isolator per phase. The MCP3910 is capable of to a variety of voltage and current sensors including shunts, current transformers, Rogowski coils and Hall effect sensors
