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.
The ADE7760 is a high accuracy, fault tolerant, electrical energy measurement IC intended for use with 2-wire distribution systems. The part specifications surpass the accuracy requirements as quoted in the IEC61036 standard. The only analog circuitry used on the ADE7760 is in the ADCs and reference circuit. All other signal processing (such as multiplication and filtering) is carried out in the digital domain.
