MCP39F501: Single-Phase, Power-Monitoring IC with Calculation and Event Detection

The MCP39F501 is a highly integrated, single-phase power-monitoring IC designed for real-time measurement of AC power. It includes two 24-bit delta-sigma ADCs, a 16-bit calculation engine, EEPROM and a flexible two-wire interface. An integrated low drift voltage reference in addition to 94.5dB of SINAD performance on each measurement channel allows accurate designs with just 0.1% error across a 4000:1 dynamic range.
