Description
General part information
MCP3910 Series
The MCP3910 is a 3V dual channel Analog-Front-End (AFE) containing two simultaneous sampling Delta-Sigma Analog-to-Digital Converters (ADC), two PGAs, phase delay compensation block (1 µs resolution), low drift (9ppm/°C) 1.2V 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. It is capable of supporting a dynamic range of 10000:1
The MCP391x portfolio of Analog Front Ends feature performance and functionality which makes them appropriate for use in designs targeted to meet the following industry standards for smart metering applications: IEC62053-11, IEC62053-21, IEC62053-22, ANSI C12.20. In such designs, the MCP391x portfolio can be paired with either MCUs/MPUs which are running a metrology engine, or standard (non-Metrology) MCUs/MPUs.
