Description

The MCP3909 device is an energy-metering IC

designed to support the IEC 62053 international meter-

ing standard specification. It supplies a frequency out-

put proportional to the average active real power, with

simultaneous serial access to ADC channels and mul-

tiplier output data. This output waveform data is avail-

able at up to 14 kHz with 16-bit ADC output and 20-bit

multiplier output words. The 16-bit, delta-sigma ADCs

allow for a wide range of IB and IMAX currents and/or

small shunt (<200 µOhms) meter designs. A no-load

threshold block prevents any current creep measure-

ments

for

the

active

power

pulse

outputs.

The integrated on-chip voltage reference has an

ultra-low temperature drift of 15 ppm per degree C.

This accurate energy metering IC with high field reli-

ability is available in the industry standard 24-lead

SSOP pinout.
