ADE7763ARSZ

The ADE7763ARSZ is a high-accuracy single-phase active and apparent energy metering integrated circuit from Analog Devices. It supports various IEC standards for energy measurement, including IEC 61036/60687, IEC62053-21, and IEC62053-22. The device features an on-chip digital integrator for direct interface with current sensors and a PGA in the current channel for interfacing with shunts and current transformers.

Key electrical characteristics include a single 5V supply voltage and a typical power consumption of 25mW. It boasts less than 0.1% error in active energy measurement over a dynamic range of 1000:1 at 25°C. The IC incorporates proprietary ADCs and a DSP for high accuracy across environmental variations. It also includes an on-chip temperature sensor with typical accuracy of ±3°C.

Designed for energy metering applications, the ADE7763ARSZ provides sampled waveform, current and voltage RMS values, and a pulse output proportional to active power. It offers digital calibration for power, phase, and input offset, along with features like positive-only energy accumulation and an internal no-load threshold to prevent creep. The device communicates via an SPI-compatible serial interface and includes an interrupt request pin.
