• AD536a

    Is it possible to use the AD536a in dBoperation fed with single supply?

  • AD536A

    I have a question in regard to the AD536A. I wanted to know what's the cut-off  frequency for this product in which it converts AC to DC and if it's tunable or not?

    I also wanted to ask what type of input format we have for this product?

  • AD536A Spice problem

    I am using AD536A in LTSpice simulation. I saw the waveform aplitude results coming correctly but the time it takes to settle does not match with what datasheet specifies.

    I am using 0.033 uF as Cav. According to datasheet I should have got around 30…

  • 输入信号为AC和AC+DC,真有效值芯片选型

    大家好!

            我想请教一个事情,关于真有效值芯片(RMS-TO-DC)的选型的。

             我的输入信号有两种,第1种是正负幅值的矩形波,频率4~25kHz;第2种是DC信号0.5~3V叠加4~25kHz的小幅值AC。我细看了3款芯片的Datasheet,分别是AD637、AD536A和AD8436。

            问一下大家:

            (1)在使用相同的CAVG的情况下,输入相同的信号(AC和AC+DC),AD637JRZ和AD536AJHZ,在精度、快速性、稳定性等方面比较,哪个更好一些?能不能相互替代?

            AD637的Datasheet图例中的对数坐标似乎没AD536A的做得好…

  • RE: Problem with AD536AK rms to DC converter

    When I isolated the output from others, the rms to dc conversion is happening correctly without offset. The problem device was identified to be ADC (AD7864BS-1) connected to the buffer output. So when i isolated ADC input from Buffer out of AD536A, the…

  • RE: RMS测量相关

    建议参考一下AD536A数据手册中,关于内部结构的部分有原理的介绍

    此外具体原理可以参考如下视频

  • About settling time by input voltage of AD8436

    Hello

    I have a question about the settling time of the AD8436.


    I think it will change depending on the capacity of the settling time CAVG.
    I think it also depends on the input voltage.

    The AD536A had a graph of settling time for the input voltage in Figure…

  • Measure true RMS or AC signal on DC offset?

    I need to measure the true RMS voltage of a Sine wave with a DC offset of two different high voltage power supplies (PS1 and PS1).

    PS1 DC offset: -6600 VDC nominal

    PS2 DC offset: -9300 VDC nominal

    Sine wave: 8.98 V peak relative to DC offset of PS1…

  • RE: RMS-to-DC for Sound Pressure Level measurement

    The AD737 averages the rms over a fixed time period as you surmised.

    ADI makes parts for audio applications such as you describe, I believe you are looking for the 'dB output' feature, where the log of the input is provided as a current sourced output…

  • Comment on AD8336_AN934带宽变化

    我认为,本电路的高端频率限制条件是用于检波器的RMS-DC转换器,低端频率限制条件是输出端的10uF电容。要将下限设置为100Mz,新电容值应是1/100*6.28*RL,其中RL是负载电阻。

    要将响应扩展到25kHz,可以测量25kHz时的响应是什么,如果对响应不满意,可以试试带宽更高的RMS-DC转换器,如AD636或AD536A等。
