ADE7932ARIZ

ADE7932ARIZ is an isolated energy metering chipset for polyphase shunt meters. It is a isolated, 3-channel sigma-delta analogue-to-digital converter (Σ-Δ ADC) for polyphase energy metering applications that use shunt current sensors. It features two ADCs. One channel is dedicated to measuring the voltage across the shunt when a shunt is used for current sensing. This channel provides a signal-to-noise ratio (SNR) of 67dB over a 3.3KHz signal bandwidth. It is approved by UL recognition 5000V rms for 1 minute per UL 1577, CSA Component Acceptance Notice 5A IEC 61010-1: 300 V rms maximum working voltage, VDE certificate of conformity, DIN V VDE V 0884-10 (VDE V 0884-10):2006-12, VIORM = 846V peak. It is used in applications such as shunt-based polyphase meters, power quality monitoring, solar inverters, process monitoring, protective devices, isolated sensor interfaces, industrial PLCs.
