ADE7752AARZ

ADE7752AARZ is an Analog Devices single‑phase energy metering IC. It integrates front‑end signal processing, digital filtering, and DSP to measure and compute electrical values for energy meters and monitors.
Key features:
- Measures Vrms and Irms, active energy (kWh), reactive energy (kVARh), and apparent energy (kVAh)
- Also provides power factor and line frequency
- Fully digital processing with SPI interface to a host MCU (SCK, SDI, SDO, CS)
- External voltage sensing and current sensing (via CT or shunt/burden resistor)
- Calibration options (gain/offset) for high accuracy
- Energy registers accumulate values for metering; suitable for digital watt-hour meters and energy monitoring
Typical use:
- Used in single-phase digital energy meters, energy monitors, and power-management devices
Note:
- AARZ is a packaging/grade suffix; refer to the datasheet for exact pinout, supply voltage (usually 3.3–5V), input ranges, and isolation requirements.

Key features of ADE7752AARZ (Single‑phase energy metering IC):
- Fully integrated single‑phase multifunction metering IC
- 24‑bit ADCs for voltage and current with on‑chip DSP
- Calculates active, reactive, and apparent energy (Wh, VARh, VAh) plus instantaneous P, Q, S and RMS values
- SPI interface for register access and energy data
- Supports 50/60 Hz (line frequency) operation; suitable for basic meter designs
- Programmable gain/input ranges; works with shunt or current transformer inputs
- On‑chip calibration: offset, gain, and phase calibration via registers
