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 24-bit  
ADCs, and the ADE7913 features three ADCs. The current ADC  
provides a 67 dB signal-to-noise ratio over a 3 kHz signal  
bandwidth, whereas the voltage ADCs provide a 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 be used to 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.
