ADE7768 is a power metering IC with integrated oscillator and positive power accumulation produced by Analog Devices
The ADE7768 is a pin‑reduced, high‑accuracy energy‑metering integrated circuit that includes an on‑chip oscillator, eliminating the need for an external crystal. It provides positive‑only average real‑power outputs (F1, F2) that can directly drive electromechanical counters or stepper motors, and a high‑frequency CF output for calibration.
The device operates from a single 5 V supply (±5 %), features on‑chip reference (2.45 V), and includes power‑supply monitoring, no‑load threshold protection, and a REVP logic output that flags negative power conditions.
| Supply Voltage (Vop) | 5 V ±5 % |
|---|---|
| On‑chip Reference Voltage | 2.45 V nominal |
| Oscillator Frequency | 450 kHz nominal |
| Channel V1 Maximum Signal Level | +30 mV max |
| Channel V2 Maximum Signal Level | +165 mV max |

The device operates from a single 5 V supply with a tolerance of ±5 %.
The on‑chip reference voltage is 2.45 V nominal.
F1 and F2 provide average positive‑only real‑power information and can directly drive electromechanical counters or 2‑phase stepper motors.
