The MCP39F511A device is a highly-integrated,complete single-phase power-monitoring IC designedfor real-time measurement of input power for AC or DCpower supplies, making it suitable for a wide range ofconsumer and industrial applications. It is capable of detecting the input voltage in order to work as DC or ACmode. It includes dual-channel Delta-Sigma ADCs, a16-bit calculation engine, EEPROM and a flexible2-wire interface. Separate AC and DC calibrationregisters are provided, to ensure high-accuracymeasurements in both modes. An integrated low-driftvoltage reference with 7 ppm/℃ in addition to 94.5 dBof SINAD performance on each measurement channelallows for better than 0.1% accurate designs across a4000:1 dynamic range.
