GENERAL DESCRIPTION

The ADE7761B 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 IEC 62053-21 standard. The only analog circuitry used on the ADE7761B is in the ADCs and reference circuit.

FEATURES

High accuracy, active energy measurement IC supports IEC 62053-21

Less than 0.1 error over a dynamic range of 1000 to 1

Supplies active power on the frequency outputs, F1 and F2

High frequency output CF is intended for calibration and supplies instantaneous active power

Continuous monitoring of the phase and neutral current allows fault detection in 2-wire distribution systems

Current channel input level best suited for shunt and current transformer sensors

Uses the larger of the two currents (phase or neutral) to bill, even during a fault condition

Continuous monitoring of the voltage and current inputs allows missing neutral detection

Uses one current input (phase or neutral) to bill when missing neutral is detected

Two logic outputs (FAULT and REVP) can be used to indicate a potential miswiring, fault, or missing neutral condition

Direct drive for electromechanical counters and 2-phase stepper motors (F1 and F2)

Proprietary ADCs and DSP provide high accuracy over large variations in environmental conditions and time

Reference 2.5 V ± 8 (drift 30 ppm/°C typical) with external overdrive capability

Single 5 V supply, low power
