This document provides preliminary technical data and functional features of Analog Devices' ADE7757 energy metering IC. The IC has high accuracy energy measurement function, integrated oscillator, and meets the accuracy requirements of IEC1036 standard. It provides average real power information on the low frequency outputs F1 and F2, which can be used to drive electromechanical counters or interface with MCUs.
The EVAL‑ADE7757EB board provides a single +5 V power supply and easy connection of external transducers via screw terminals. It includes on‑board antialias filters, a trim‑pot for analog calibration, and optically isolated outputs for testing and calibration.
The document explains how to set up the analog inputs, configure logic outputs, select output frequencies, and convert the board into a functional energy meter by adding a power supply and current sensor. Detailed jumper settings and a complete bill of material are also provided.
| Power Supply Voltage | +5 V |
|---|---|
| Integrated Oscillator | Clock source for the chip |
| Trim Pot R15 | 100 Ω, 10 %, 1/2 W |
| Maximum Current | 25 A |
All analog input signals are filtered using the on‑board antialias filters before reaching the ADE7757.
By adding a local power supply, connecting a suitable current sensor, and setting the appropriate jumpers, the evaluation board can function as an energy meter.
