Description
The MCP3909 device is an energy-metering IC
designed to support the IEC 62053 international metering standard specification. It supplies a frequency output proportional to the average active real power, with
simultaneous serial access to ADC channels and multiplier output data. This output waveform data is available 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 measurements 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 reliability is available in the industry standard 24-lead
SSOP pinout.
