ADE7753ARSZ

The Analog Devices ADE7753ARSZ is a single-phase multifunction metering integrated circuit. It is designed for high accuracy, supporting various IEC standards and offering less than 0.1% error in active energy measurement over a dynamic range of 1000 to 1 at 25°C.

This IC incorporates proprietary ADCs and DSP for precise measurements across varying environmental conditions. Key features include an on-chip digital integrator for direct interface with current sensors, a PGA for shunts and current transformers, and digital calibration for power, phase, and input offset. It also includes an on-chip temperature sensor with typical ±3°C accuracy.

The ADE7753ARSZ operates from a single 5V supply with a typical power consumption of 25mW. It communicates via an SPI-compatible serial interface and provides a pulse output proportional to active power. The device is housed in a 20-SSOP surface mount package.

This metering IC is suitable for applications requiring accurate energy measurement, including smart meters and power monitoring systems. Its features like voltage surge and SAG detection, positive-only energy accumulation, and an internal no-load threshold enhance its utility in diverse power management scenarios.
