The MCP39F511A device is a highly-integrated, complete single-phase power-monitoring IC designed for real-time measurement of input power for AC and DC power supplies, making it suitable for a wide range of consumer and industrial applications. It is capable of detecting the input voltage types in order to select DC or AC mode automatically. It includes dual-channel Delta-Sigma ADCs, a 16-bit calculation engine, EEPROM and a flexible 2-wire interface. Separate AC and DC calibration registers are provided, to ensure high-accuracy measurements in both modes. An integrated low-drift voltage reference with 7 ppm/°C in addition to 94.5 dB of SINAD performance on each measurement channel allows for better than 0.1% accurate designs across a 4000:1 dynamic range.
