GENERAL DESCRIPTION

The ADE7912/ADE79131 are isolated, 3-channel Σ-Δ ADCs for polyphase energy metering applications using shunt current sensors. Data and power isolation are based on the Analog Devices, Inc., iCoupler? technology. The ADE7912 features two ADCs, and the ADE7913 features three ADCs. The current ADC provides a 67 dB signal-to-noise ratio (SNR) over a 3 kHz signal bandwidth, whereas the voltage ADCs provide an SNR of 72 dB 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 measure the temperature of the die via an internal sensor. The ADE7913 includes three channels: one current and two voltage channels. The ADE7912 has one voltage channel but is otherwise identical to the ADE7913.
