ADE7763屬于集成電路（IC）的電能計量。由亞德諾半導體技術有限公司制造生產的ADE7763電能計量能量計量集成電路可用于單相、雙相和三相電力線系統(tǒng)中的高精度電能測量。這些器件可以測量線路電壓和電流，并且可以計算有功、無功和視在電能，以及瞬時均方根電壓和電流。

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.
