Overview

Product Highlight

  • Wh Accuracy: 0.1 %
  • Dynamic Range: 1000 to 1 dB
  • Interface: SPI

The MCP3909 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 simultaneous serial SPI interface to access the ADC channels and multiplier output data.

The MCP3909 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 output waveform data is available at up to 14 kHz with 16-bit ADC output and 20-bit multiplier output data. The integrated on-chip voltage reference has an ultra-low temperature drift of 15 ppm per degree C. 

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, DAC, 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.)
  • Active power pulse output
  • SPI™ interface for access to raw ADC and multiplier data
