ADE7755 is a digital-to-frequency converter for power measurement. It has high accuracy, high dynamic range, direct drive motor, small load resistance, and can directly drive motors and stepper motors.
The ADE7755 is a 24‑lead SSOP energy‑metering integrated circuit that provides average real‑power information on low‑frequency outputs F1 and F2 and instantaneous power on the high‑frequency CF output. It features a PGA for current‑channel gain selection, on‑chip 2.5 V reference (±8 %), and built‑in power‑supply monitoring and creep protection.
The device operates from a single 5 V supply (4.75 V – 5.25 V) with a typical power dissipation of 450 mW, and is rated for industrial temperature ranges (‑40 °C – +85 °C). Pin‑compatible with the AD7755, it adds synchronous CF and F1/F2 outputs under all load conditions, making it suitable for precise IEC‑1036 compliant energy‑meter designs.

The device operates from 4.75 V min to 5.25 V max, which is 5 V ± 5 %.
It is offered in a 24‑lead SSOP package with pins numbered 1‑24 as shown in the pin configuration table.
The CF output provides instantaneous real‑power information and is intended for calibration or high‑speed MCU interfacing.
