EVAL-ADE7752AEBZ 评估板
ADE7752A是一款适合用于三相配电系统的精确有功功率电能计量IC。它可根据输电线的电流和电压提供瞬时有功功率和平均有功功率。该器件规范超过IEC61036标准规定的精度要求。ADE7752A中使用的唯一模拟电路是ADC和参考电压电路。所有其它信号处理（例如乘法和滤波）都是在数字域实现的。这种信号处理方法可在随环境条件和时间变化的很大范围内提供优异的稳定性和精度。
通道之间的增益校准在器件外部进行调整。ADE7752A采用24引脚SOIC封装。ADE7752A的功耗低于ADE7752。推荐选用ADE7752A用于全新的设计,它并且可以直接替代ADE7752。这两款产品的功能和引脚相互兼容。
ADE7752A 脉冲输出低功耗三相电能计量IC
The ADE7752 is a high accuracy polyphase electrical energy measurement IC. The ADE7752A is a pin-to-pin compatible low power version of ADE7752. The functions of ADE7752 and ADE7752A are the same. Both products are referred to in the text of this data sheet as ADE7752.
The part specifications surpass the accuracy requirements as quoted in the IEC62053-2x standard. The only analog circuitry used in the ADE7752 is in the analog-to-digital converters (ADCs) and reference circuit. All other signal processing (such as multi-plication, 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。
The ADE7752 supplies average real power information on the low frequency outputs, F1 and F2. These logic outputs may be used to directly drive an electromechanical counter or to interface with an MCU. The CF logic output gives instanta-neous real power information. This output is intended to be used for calibration purposes.
The ADE7752 includes a power supply monitoring circuit on the VDD pin. The ADE7752 remains inactive until the supply voltage on VDD reaches 4 V. If the supply falls below 4 V, no pulses are issued on F1, F2, and CF. Internal phase matching circuitry ensures that the voltage and current channels are phase matched. An internal no load threshold ensures the part does not exhibit any creep when there is no load. The ADE7752 is available in a 24-lead SOIC package.
