ADE9103/ADE9112/ADE9113 Isolated Sigma-Delta ADCs

Analog Devices ADE9103/ADE9112/ADE9113 Isolated Sigma-Delta ADCs feature precision simultaneously sampling Σ-Δ for both DC and polyphase shunt-based energy metering applications. The ADE91131 integrates safety certified signal and power galvanic isolation with three simultaneously sampling fully differential 24-bit Σ-Δ ADC channels. The ADE9112 offers two fully differential Σ-Δ ADC channels for isolated applications where only a single voltage channel is required. The ADE9103 is a nonisolated, 3-channel Σ-Δ ADC for use in applications without isolation, such as neutral measurement.
