ADE7913:  3-Channel, Isolated, Sigma Delta ADC with SPI

Product Details

Product Status:Recommended for New Designs

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 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
