The ADE7913ARIZ is a 3-channel isolated sigma-delta Analog-to-digital Converter (ADC) with SPI for poly-phase energy metering applications using shunt current sensors. Data and power isolation are based on the Analog Devices Inc, iCoupler® technology. The current ADC provides a 67dB signal-to-noise ratio over a 3kHz signal bandwidth whereas the voltage ADC provides an SNR of 72dB over the same bandwidth. One channel is dedicated to measuring the voltage across a shunt when the shunt is used for current sensing. Up to two additional channels are dedicated to measuring voltages, which are usually sensed using resistor dividers. One voltage channel can be used to measure the temperature of the die via an internal sensor.
• Integrated isoPower, isolated DC-to-DC converter
