Description
GENERAL DESCRIPTION
The ADE77631 features proprietary ADCs and fixed function DSP for high accuracy over large variations in environmental conditions and time. The ADE7763 incorporates two second order, 16-bit Σ-∆ ADCs, a digital integrator (on Ch1), reference circuitry, a temperature sensor, and all the signal processing required to 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.
FEATURES
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
On-chip temperature sensor (±3°C typical)
SPI®-compatible serial interface
Pulse output with programmable frequency
Interrupt request pin (IRQ) and status register
Reference 2.4 V with external overdrive capability
