Product Description

The AD71056ARZ is a high accuracy, Electrical Energy Metering IC with a precise oscillator circuit that serves as a clock source to the chip. The device eliminates the need for an external crystal or resonator, thus reducing the overall cost of building a meter with this IC. The chip directly interfaces with the shunt resistor. The only analog circuitry used in the device is in the Σ-Δ ADCs and reference circuit. All other signal processing, such as multiplication and filtering, is carried out in the digital domain. This approach provides superior stability and accuracy over time and in extreme environmental conditions. These outputs either directly drive an electromechanical counter or interface with an MCU. Internal phase matching circuitry ensures that the voltage and current channels are phase matched and the HPF in the current channel eliminates DC offsets. An internal no load threshold ensures that the AD71056 does not exhibit creep when no load is present.
On-chip oscillator as clock source
High accuracy, supports 50Hz/60Hz 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 variations in environmental conditions/time
On-chip power supply monitoring
On-chip creep protection (no load threshold)
On-chip reference 2.45V (20ppm/°C typical) with external overdrive capability
CMOS process
