ADE7769 is an energy metering IC with integrated oscillator and no-load indication
The ADE7769 is a high‑accuracy energy‑metering integrated circuit with an on‑chip oscillator and no‑load indication. It provides average real‑power outputs for driving electromechanical counters or stepper motors and a high‑frequency output for instantaneous power calibration.
The document includes functional description, pin configuration, timing characteristics, absolute maximum ratings, typical performance curves, power‑supply monitoring, and guidelines for selecting frequency and handling no‑load conditions.
| Supply Voltage (Vop) | 5 V ±5% |
|---|---|
| Operating Temperature Range | ‑40 °C to +85 °C |
| Channel V1 Maximum Signal Level | +30 mV max |
| On‑chip Reference Voltage | 2.45 V nominal |
| Oscillator Frequency | 450 kHz nominal |
The device remains inactive until the supply voltage on Vpp reaches approximately 4 V; normal operation requires Vop of 5 V ±5%.
The ADE7769 is supplied in a 16‑lead narrow‑body SOIC package.
