ADE7762ARWZ集成电路（IC）的电能计量规格书PDF中文资料

ADE7762ARWZ属于集成电路（IC）的电能计量。由亚德诺半导体技术有限公司制造生产的ADE7762ARWZ电能计量能量计量集成电路可用于单相、双相和三相电力线系统中的高精度电能测量。这些器件可以测量线路电压和电流，并且可以计算有功、无功和视在电能，以及瞬时均方根电压和电流。

GENERAL DESCRIPTION

The ADE77621 is a high accuracy polyphase electrical energy measurement IC. The ADE7762 specifications surpass the accuracy requirements as quoted in the IEC62053-21 standard.

The only analog circuitry used in the ADE7762 is in the analog-to-digital converters (ADCs) and reference circuit. All other signal processing (for example, multiplication, filtering, and summation) is carried out in the digital domain. This approach provides superior stability and accuracy over extremes in environmental conditions and over time.

FEATURES

High accuracy supports 50 Hz/60 Hz IEC62053-21

Less than 0.1 error over a dynamic range of 500 to 1

Compatible with 3-phase 3-wire delta and 3-phase 4-wire Wye

configurations

Supplies average active power on the frequency outputs F1 and F2

High frequency output (CF) is intended for calibration and

supplies instantaneous active power

Logic output REVP indicates a potential miswiring or negative

power on the sum of all phases

Dropout indication for each phase on LED driver pins

Phase sequence error detection

Direct drive for electromechanical counters and 2-phase stepper

motors (F1 and F2)

Proprietary ADCs and DSP provide high accuracy over large

variations in environmental conditions and time

On-chip power supply monitoring

On-chip creep protection (no load threshold)

On-chip reference 2.4 V ± 8 (25 ppm/°C typical) with external

overdrive capability

Single 5 V supply, low power (TBD mW typical)

Low cost CMOS process
