The ADE7912/ADE7913 are isolated, 3-channel Σ-Δ ADCs for a variety of applications such as shunt-based polyphase meters, power quality monitoring, solar inverters, process monitoring and protective devices. 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 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.

Product Lifecycle Production
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
Evaluation Kits (1)
The ADE7913 evaluation kit includes three boards that together allow the performance of the ADE7913 isolated sigma delta ADC to be evaluated in a context very close to an actual three phase meter implementation. The ADE7913 evaluation kit includes evaluation software, written in LabVIEW®, that provides access to the registers of every ADE7913 using a PC interface.
The file contains the evaluation board schematic, the bill of materials of the board, the layout files and the ADE7913 evaluation software installation files.
