Features & Applications

Microchip Technology Inc. is a leading provider of microcontroller and analog semiconductors, providing low-risk product development, lower total system cost and faster time to market for thousands of diverse customer applications worldwide. Headquartered in Chandler, Arizona, Microchip offers outstanding technical support along with dependable delivery and quality.

The MCP3905A is an energy measurement IC supporting the IEC 62053 international energy metering specification. The output of the device includes a frequency proportional to the average active (real) power at the inputs as well as a higher frequency output proportional to the instantaneous power for meter calibration. The MCP3905A incorporates two 16-bit delta-sigma ADCs with a progammable gain up to 16, which enable small shunt meter designs for measuring a wide range of Ib and Imax currents. The integrated on-chip voltage reference has ultra-low temperature drift of 15 ppm/°C. Also on-chip is a fixed-function DSP for active (real) power calculation.

Features:

  • Supplies active (real) power measurement for single-phase, residential energy metering
  • Supports IEC 62053 International Energy Metering Specification and legacy IEC 1036/61036/687   Specifications
  • Two multi-bit, Analog-to-Digital Converters (ADCs), second-order, 16-bit, Delta-Sigma Analog-to-Digital Converters (ADCs)
  • Ultra-low drift on-chip reference: 15 ppm/°C (typ.)
  • Low IDD of 4 mA (typ.) 

The MCP3905A-I/SS is available in a SSOP 208Mil 24-Pin package with a temperature range of -40°C to +85°C.
