ADE7932/ADE7933 Isolated, Sigma Delta ADCs

Analog Devices Inc. ADE7932/ADE7933 Isolated Sigma-Delta Analog-to-Digital Converters (Σ-Δ ADCs) for polyphase energy metering applications that use shunt current sensors. ADE7932 features two 24-bit ADCs, while the ADE7933 features three 24-bit ADCs. One channel is dedicated to measuring the voltage across the shunt when a shunt is used for current sensing. This channel has a signal-to-noise ratio (SNR) of 67dB over a 3.3kHz signal bandwidth. Up to two additional channels are dedicated to measuring voltages, which are usually sensed using resistor dividers. These channels provide an SNR of 75dB over a 3.3kHz signal bandwidth. One voltage channel can be used to measure the temperature of the die via an internal sensor.
