Single-Phase Multifunction Metering IC
with di/dt Sensor Interface
ADE7753
line-voltage period measurement, and rms calculation on the
voltage and current. 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 voltage channels. FEATURES
High accuracy; supports IEC 60687/61036/61268 and
IEC 62053-21/62053-22/62053-23
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, reactive, and apparent energy; sampled waveform;
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
On-chip temperature sensor (±3°C typical) …
