Analog Devices ADE7760 Manuals

ADE7760 is a high accuracy energy measurement IC that supports IEC 687/61036 standard, dynamic range of 500:1, error less than 0.1%, frequency output terminal F1 and F2 can output active power, high frequency output terminal CF is used for calibration, can output instantaneous active power, in the two-wire distribution system, continuous monitoring of phase current and neutral current can realize fault detection, current channel input level is best suited for current transformer sensors, in fault state, larger current (phase current or neutral current) is used for billing, two logic outputs (FAULT and REVP) can be used to indicate potential wiring errors or fault conditions, can directly drive electromechanical counters and two-phase stepper motors (F1 and F2), proprietary ADC and DSP can provide high precision oversampling measurement.

This document introduces the ADE7760 energy metering IC with on-chip fault detection. It supports IEC 687/61036 standards and features high accuracy active energy measurement with less than 0.1% error over a dynamic range of 500 to 1. The IC provides active power on the frequency outputs F1 and F2, and the high frequency output CF is used for calibration and supplies instantaneous active power. It continuously monitors the phase and neutral current for fault detection in 2-wire distribution systems. The current channels are designed for current transformer sensors, and the larger of the two currents (phase or neutral) is used for billing, even during a fault condition. It also has two logic outputs (FAULT and REVP) that can indicate potential miswiring or fault conditions. The IC supports direct drive for electromechanical counters and 2-phase stepper motors.

ADE7760 is a high-accuracy active energy measurement IC produced by Analog Devices. It supports the IEC 687/61036 standard and has a dynamic range of 500:1. The output frequency is F1 and F2, and the high-frequency output CF is used for calibration and provides instantaneous active power. In addition, it can monitor the phase current and neutral current to realize fault detection in 2-wire distribution systems.
