AD7755 - Energy Metering IC with Pulse Output

Datasheet Summary

Description

The AD7755 is a high accuracy electrical energy measurement IC.

The part specifications surpass the accuracy requirements as quoted in the IEC1036 standard.

See Analog Devices’ Application Note AN-559 for a description of an IEC1036 watt-hour meter reference design.

Features

  • High Accuracy, Supports 50 Hz/60 Hz IEC 687/1036 Less than 0.1% Error Over a Dynamic Range of 500 to 1 The AD7755 Supplies Average Real Power on the Frequency Outputs F1 and F2 The High Frequency Output CF Is Intended for Calibration and Supplies Instantaneous Real Power The Logic Output REVP Can Be Used to Indicate a Potential Miswiring or Negative Power Direct Drive for Electromechanical Counters and Two Phase Stepper Motors (F1 and F2) A PGA in the Current Channel Allows the Use of Small Valu.
