Product Summary

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. The chip directly interfaces with the shunt resistor.

Parametrics

AD71056 absolute maximum ratings: (1)VDD to AGND: –0.3 V to +7 V; (2)VDD to DGND: –0.3 V to +7 V; (3)Analog Input Voltage to AGND V1P, V1N, V2P and V2N: –6 V to +6 V; (4)Reference Input Voltage to AGND: –0.3 V to VDD + 0.3 V; (5)Digital Input Voltage to DGND: –0.3 V to VDD + 0.3 V; (6)Digital Output Voltage to DGND: -0.3 V to VDD + 0.3 V; (7)Operating Temperature Range: –40°C to +85°C; (8)Storage Temperature Range: –65°C to +150°C; (9)Junction Temperature: +150°C.

Features

AD71056 features: (1)On-chip oscillator as clock source; (2)High accuracy, supports 50 Hz/60 Hz IEC62053-21; (3)Less than 0.1% error over a dynamic range of 500 to 1; (4)Supplies average real power on frequency outputs (F1, F2); (5)High frequency output (CF)calibrates and supplies instantaneous real power; (6)Logic output (REVP)indicates potential miswiring or negative power; (7)Direct drive for electromechanical counters and 2-phase stepper motors (F1, F2); (8)Proprietary ADCs and DSP provide high accuracy over large variations in environmental conditions and time; (9)On-chip power supply monitoring; (10)On-chip creep protection (no load threshold); (11)On-chip reference 2.45 V (20 ppm/°C typical)with external overdrive capability; (12)Single 5 V supply, low power.
