ADE7769ARZ屬于集成電路（IC）的電能計(jì)量。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的ADE7769ARZ電能計(jì)量能量計(jì)量集成電路可用于單相、雙相和三相電力線系統(tǒng)中的高精度電能測(cè)量。這些器件可以測(cè)量線路電壓和電流，并且可以計(jì)算有功、無功和視在電能，以及瞬時(shí)均方根電壓和電流。

GENERAL DESCRIPTION

The ADE7769 is a high accuracy electrical energy metering IC. It is a pin reduction version of the ADE7755 with an enhanced, precise oscillator circuit that serves as a clock source to the chip. The ADE7769 eliminates the cost of an external crystal or resonator, thus reducing the overall cost of a meter built with this IC. The chip directly interfaces with the shunt resistor.

FEATURES

On-chip oscillator as clock source

High accuracy, supports 50 Hz/60 Hz IEC62053-21

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

Supplies average real power on frequency outputs F1 and F2

High frequency output CF calibrates and supplies instantaneous real power

CF output remains logic high when ADE7769 is under no-load threshold

Logic output REVP indicates a potential miswiring or negative power

Direct drive for electromechanical counters and 2-phase stepper motors (F1 and F2)

Proprietary ADCs and DSPs 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 2.45 V (20 ppm/°C typical) with external overdrive capability

Single 5 V supply, low power (20 mW typical)

Low cost CMOS process
