The ADE7754 is a polyphase multifunction energy metering IC with high accuracy and support for various types of three-phase energy services. It can measure multiple parameters of energy and has less than 0.1% error in active power measurement.
The ADE7754 is a polyphase multifunction energy‑metering IC designed for 3‑phase power‑meter services. It integrates second‑order X‑ADC, on‑chip reference, temperature sensor and a serial SPI interface, providing active, apparent, voltage RMS, current RMS and waveform data.
Key features include less than 0.1 % active‑power error over a 1000:1 dynamic range, programmable voltage‑sag and over‑drive detection, a pulse output with programmable frequency, and a single 5 V supply. The device is supplied in a 24‑lead SOIC package and supports a 10 MHz master clock.
| Active Power Measurement Error | 0.1 % typ |
|---|---|
| Supply Voltage (AVpp) | 4.75 V min to 5.25 V max (5 V ± 5%) |
| On‑Chip Temperature Sensor Accuracy | +4 °C typical after calibration |
The device operates from 4.75 V minimum to 5.25 V maximum, which is 5 V ± 5%.
IRQ is an active‑low, open‑drain logic output that goes low when an interrupt condition occurs.
The ADE7754 is available in a 24‑lead SOIC package.
The CLKIN input expects a 10 MHz clock for typical operation.
