GENERAL DESCRIPTION

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.

FEATURES

High accuracy active energy measurement IC, supports

IEC 687/61036

Less than 0.1 error over a dynamic range of 500 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 channels input level best suited for current

transformer sensors

Uses the larger of the two currents (phase or neutral) to

bill—even during a fault condition

Two logic outputs (FAULT and REVP) can be used to indicate

a potential miswiring or fault 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
