AEC-Q100, Energy Metering IC, 16 Bit Dual ADC, 4.5 V to 5.5 V, SSOP-24

Product Overview
The MCP3909-I/SS is an Energy Metering IC with SPI interface, active power pulse output and high field reliability. It is 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 up to 14kHz with 16-bit ADC output and 20-bit multiplier output words. The 16-bit, delta-sigma ADC allows for a wide range of IB and IMAX currents or small shunt (<200µOhms) 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 15ppm/°C.
