ADE7753ARSZ

ADE7753 is a proprietary ADC and DSP for high accuracy over large variations in environmental conditions and time. The ADE7753 incorporates two second-order 16-bit Σ-Δ ADCs, a digital integrator(on CH1), reference circuitry, temperature sensor and all the signal processing required to perform active, reactive, and apparent energy measurements, 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. The ADE7753 provides a serial interface to read data, and a pulse output frequency(CF), which is proportional to the active power. Various system calibration features, i.e., channel offset correction, phase calibration, and power calibration, ensure high accuracy.

• 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
• Less than 0.1% error in active energy measurement over 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
• On-chip temperature sensor (±3°C typical) and SPI® compatible serial interface
• Pulse output with programmable frequency and reference 2.4V with external overdrive capability
• Single 5V supply, low power (25mW typical)
• 20 lead SSOP package, operating temperature range from -40°C to 85°C
