ADE7953ACPZ

ADE7953 is a high accuracy electrical energy measurement IC intended for single phase applications. It measures line voltage and current and calculates active, reactive and apparent energy, as well as instantaneous rms voltage and current. 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.
