Description
AI
The MCP39F501 is a highly integrated, single-phase power-monitoring IC designed for real-time measurement of input power for AC/DC power supplies, power distribution units and industrial applications. It includes dual-channel delta sigma ADCs, a 16-bit calculation engine, EEPROM and a flexible 2-wire interface. An integrated low-drift voltage
reference 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.
