Additional preview pages of the AD71056 datasheet.

The AD71056 is a high accuracy, electrical energy metering IC with a precise oscillator circuit that serves as a clock source to the chip.

The AD71056 eliminates the need for an external crystal or resonator, thus reducing the overall cost of building a meter with this IC.

On-chip oscillator as clock source High accuracy, supports 50 Hz/60 Hz IEC62053-21 Less than 0.1% error over a dynamic range of 500 to 1 Supplies average real power on frequency outputs (F1, F2) High frequency output (CF) calibrates and supplies instantaneous real power Logic output (REVP) indicates potential miswiring or negative power Direct drive for electromechanical counters and 2-phase stepper motors (F1, F2) Proprietary ADCs and DSP provide high accuracy over large variations in environme.
