Single-Phase Active and Apparent
Energy Metering IC
ADE7763 Data Sheet
FEATURES perform active and apparent energy measurements, line-voltage
period measurements, and rms calculation on the voltage and
current channels. The selectable on-chip digital integrator
provides direct interface to di/dt current sensors such as
Rogowski coils, eliminating the need for an external analog
integrator and resulting in excellent long-term stability and precise
phase matching between the current and the voltage channels. High accuracy; supports IEC 61036/60687, IEC62053-21, and
IEC62053-22
On-chip digital integrator enables direct interface-to-current
sensors with di/dt output
A PGA in the current channel allows direct interface to
shunts and current transformers
Active and apparent energy, sampled waveform, and current
and voltage rms
Less than 0.1% error in active energy measurement over a
dynamic range of 1000 to 1 at 25°C
Positive-only energy accumulation mode available
On-chip user programmable threshold for line voltage surge
and SAG and PSU supervisory
Digital calibration for power, phase, and input offset …
