The MCP39F501 single-phase power-monitoring IC is designed for real-time measurement of ac power. It includes two 24-bit delta-sigma ADCs, a 16-bit calculation engine, EEPROM and a two-wire interface. An integrated low-drift voltage reference in addition to 94.5 dB of SINAD performance on each measurement channel allows accurate designs with 0.1 % error across a 4000:1 dynamic range. Additionally, operating temperature ranges from -40°C to +125°C. The MCP39F501 is available now for sampling and volume production in 28-lead QFN 5 mm x 5 mm packages for $1.82 each/5,000.
