MCP39F511N-E/MQ

The MCP39F511N is a highly integrated, complete dual-channel single-phase power-monitoring IC designed for real-time measurement of input power for dual-socket wall outlets, power strips, and consumer and industrial applications. It includes dual-channel 24-bit Delta-Sigma ADCs for dual-current measurements, a 10-bit SAR ADC for voltage measurement, a 16-bit calculation engine, EEPROM and a flexible two-wire interface. An integrated low-drift voltage reference with 10 ppm/°C in addition to 94.5 dB of SINAD performance on each measurement channel allows for better than 0.5% accurate designs across a 4000:1 dynamic range.
