• AD8032的问题

    我想问下,这个AD8032ARM这款芯片能否工作在3.3v下,我看数据手册写的是2.7V,5V。不知道3.3V可不可以工作

  • ad8032仿真模型的问题

    使用ad8032a.cir模型做搭建电压同相放大器仿真时出现如下现象:

    (1)仿真电路使用单电源+5V供电时,运放输出端电压值始终是电源电压。

    (2)仿真电路使用双电源±5V供电时,运放输出端电压值正常。

    问题:datasheet中显示,ad8032a既可以单电源供电,又可以双电源供电,为什么会出现上述现象。

  • Differential input voltage of opamp ±0.8 V

    Hi

    In AD8022 datasheet has Differential Input Voltage  ±0.8 V at absolute maximum rating.

    In design i provided the supply voltage as  +/-12V.

    i used the amplifier as Voltage follower,inverting amplifier and active filter.

    Inverting Amplifier and Filters…

  • RE: AD7767:  How is the maximun input current on the VREF  Pin?

    Hi Jonathan,

    We have two AD7767 in our application and  want to use one reference only.

    Figure 46 in the Datasheet Rev.0 is differ to Datasheet Rev.C.

    Can the reference ADR434 drive 100μF ?

    Should a separate reference be used for each AD7767 or is…

  • RE: AD7699评估板

    1. R46并没有明确的作用,可能方便调试用; R53与C58组成低通滤波, 为AD7699的抗混跌滤波器。

    2. R26与C38是低通滤波器;R28与R26相同为了减小运放AD8032的偏置电流引起的额外输出offset.

  • The unusual distortion of AD8031

    Dear Sir/Madam,

    We would like to use AD8031ANZ for  a unity gain follower.
    Pls refer to the schematic. below,

    There are description on the datasheet.

  • 关于AD8302的使用问题

    各位老师专家好,我刚接触这方面的东西有些不太明白的地方,谢谢大家的帮助。


    我想将AD8032用作鉴相器,有以下两个个问题:


    1、芯片鉴相输出端输出的信号是与两路输入信号相位差成正比的直流电压,还是

    需要加环路滤波器才行;


    2、是否有实现鉴相功能的现成评估板,大概多少钱

  • RE: AD7367-5 circuit diagrams

    Hi,Gnib.

      The figure below is latest tested(November 17th) AD7367-5 serial digital output on DOUTA pin1 for five range ±1/±2/±3/±4/±5V all-frequence-10kHz Sinusoidal inputs about V1.And the AGND to V1 is connected to the analog ground plane of the system…

  • RE: Need Help in selection of ADC for CMOS Image Sensor

    No , the sensor output is a differential one, it has two outputs vout+ and vout-, Vcm is 2V and output varies +/- 400mV

    if seen as differential input the swing is 400mV

    basically the data is an image data from sensor, so i feel the data wont change that…

  • AD8302 is not working

    Hello everybody,

    i am building a QCM (Quarz crystall microbalance). The concept is similiar to this: https://openqcm.com/about-openqcm-q-1. I am using a AD9850 DDS Signalgenerator, who generate a sinuidal signal. This Signal should actuate the crystall…
