Energy Metering IC with Integrated
Oscillator and Positive Power Accumulation
ADE7768
The ADE7768 specifications surpass the accuracy requirements of the IEC62053-21 standard. The AN-679 Application
Note can be used as a basis for a description of an IEC61036
(equivalent to IEC62053-21) low cost, watt-hour meter
reference design. FEATURES
On-chip oscillator as clock source
High accuracy, supports 50 Hz/60 Hz IEC62053-21
Less than 0.1% error over a dynamic range of 500 to 1
Supplies positive-only average real power on frequency
outputs F1 and F2
High frequency output CF calibrates and supplies
instantaneous, positive-only real power
Logic output REVP indicates potential miswiring or negative
power
Direct drive for electromechanical counters and 2-phase
stepper motors (F1 and F2)
Proprietary ADCs and DSPs provide high accuracy over
large variations in environmental conditions and time
On-chip power supply monitoring
On-chip creep protection (no-load threshold)
On-chip reference 2.45 V (20 ppm/°C typical) with …
