Microchip Technology's MCP39F511A device is a complete single-phase, highly integrated, power-monitoring IC designed for real-time measurement of input power for AC or DC power supplies. 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. The MCP39F511A comes in a 5x5 QFN package. The rich feature-set of this device makes it suitable for a wide range of consumer and industrial applications including power supplies, home IoT devices, industrial power meters, and commercial lighting.
