ADE7903 Datasheet Sigma-Delta ADC

Manufacturer: Analog Devices

General Description

The ADE7903 is a nonisolated, 3-channel, Σ-Δ analog-to-digital converter (ADC) for the neutral line of polyphase energy metering applications using shunt current sensors.

The ADE7903 can also be used for single-phase energy metering and other standalone ADC applications.
