ADI ADE7756AN

0.1%4.75 V ~ 5.25 VSingle Phase

Overview

The ADE7756AN is a high-accuracy electrical power measurement IC with a serial interface and a pulse output. The ADE7756AN incorporates two second-order sigma-delta ADCs, reference circuitry, temperature sensor, and all the signal processing required to perform active power and energy measurement. The ADE7756AN contains a sampled Waveform register and an Active Energy register capable of holding at least five seconds of accumulated power at full load. Data is read from the ADE7756AN via the serial interface. The ADE7756AN also provides a pulse output (CF) with a frequency that is proportional to the active power.

High Accuracy, Supports IEC 687/1036 Less than 0.1% Error over a Dynamic Range of 1000 to 1 An On-Chip User Programmable Threshold for Line Voltage SAG Detection and PSU Supervisory The ADE7756 Supplies Sampled Waveform Data (20 Bits) and Active Energy (40 Bits) Digital Power, Phase and Input Offset Calibration An On-Chip Temperature Sensor (3C Typical after Calibration) An SPI-Compatible Serial Interface A Pulse Output with Programmable Frequency An Interrupt Request Pin (IRQ) and Status Register Provide Early Warning of Register Overflow and Other Conditions Proprietary ADCs and DSP Provide High Accuracy over Large Variations in Environmental Conditions and Time Reference 2.4 V 8% (20 ppm/C Typical) with External Overdrive Capability Single 5 V Supply, Low Power (25 mW Typical)
