Datasheet Analog Devices ADE7953ACPZ-RL — Datenblatt

Single Phase, Multifunction Metering IC
with Neutral Current Measurement
ADE7953 Data Sheet The device incorporates three Σ-Δ ADCs with a high accuracy
energy measurement core. The second input channel simultaneously measures neutral current and enables tamper detection
and neutral current billing. The additional channel incorporates
a complete signal path that allows a full range of measurements.
Each input channel supports independent and flexible gain stages,
making the device suitable for use with a variety of current sensors
such as current transformers (CTs) and low value shunt resistors.
Two on-chip integrators facilitate the use of Rogowski coil sensors. FEATURES
