ADE7763:  单相有功和视在功率计量IC

产品详情

ADE7763配备专有ADC和固定功能DSP,可在变化较大的环境条件下长期保持高精度特性。ADE7763内置两个二阶16位Σ-Δ型ADC、一个数字积分器(在通道1上)、基准电压源电路、一个温度传感器及所有必需的信号处理电路,可执行有功和视在功率测量、线路电压周期测量以及电压和电流通道均方根值的计算。可选片内数字积分器可以直接与罗氏线圈等di/dt电流传感器接口,因而无需外部模拟积分器,并且可提供出色的长期稳定性以及电流和电压通道之间的精密相位匹配。

ADE7763配有一个串行接口,可用来读取数据及与有功功率成比例的脉冲输出频率(CF)。它提供通道失调校正、相位校准和功率校准等各种系统校准功能,确保高精度测量。该器件还能检测短路持续时间、低压或高压变化。

在仅累计正功率模式下,器件仅在检测到正功率时才累计功率。内部空载阈值确保空载时器件不会出现爬电现象。零交越输出(ZX)产生一个与线路电压的零交越点同步的脉冲。在周期有功和视在功率累计模式下,器件内部会使用该信号以加快校准。

中断状态寄存器指示中断的性质,中断使能寄存器控制何种事件在IRQ 引脚上产生输出(开漏、低电平有效逻辑输出)。

ADE7763采用20引脚SSOP封装。
