Product Overview

The MCP3905A-I/SS is an Energy Metering IC with active real power pulse output 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 programmable gain up to 16, enables 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 15ppm/°C.
  • Supplies active (real) power measurement for single-phase, residential energy metering
  • Supports legacy IEC 1036/61036/687
  • Two multi-bit, DAC, second-order, 16-bit, delta-sigma analogue-to-digital converters (ADCs)
  • 0.1% Typical measurement error over 500:1 dynamic range
  • Programmable gain amplifier (PGA) for small signal inputs supports low value shunt current sensor
  • Direct drive for electromagnetic mechanical counter and two-phase stepper motors
  • Low IDD of 4mA (typical)
  • Tamper output pin for negative power indication
  • Supplies instantaneous real power on HFOUT for meter calibration
