MCP39F511 Energy Measurement ICs
The MCP39F511 from Microchip is an integrated, single-phase power monitoring device that provides real-time measurement of input power and energy values for AC/DC power supplies. On-board are two Delta-Sigma Analogue-to-Digital Converters (ADCs), a 16-bit Calculation Engine, EEPROM and a flexible 2-Wire Interface. An integrated low-drift voltage reference, combined with the 94.5 dB of SINAD performance on each measurement channel, allows for better than 0.1% accurate designs across a 4000:1 dynamic range.
