ADI's ADE7953 is a high-accuracy, electrical energy measurement IC intended for single-phase applications. It measures line voltage and current and calculates active, reactive, apparent energy, and instantaneous V_RMS and current.

The device incorporates three sigma delta ADCs with a high-accuracy energy measurement core. The third 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 (CT’s) and low-value shunt resistors. Two on-chip integrators facilitate the use of Rogowski coil sensors.
