• 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

  • 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…

  • 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.
    /P.14:
    Used as a unity gain follower, the output of the AD8031/
    AD8032 exhibits more distortion in the peak…

  • 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.

  • AD8138 not working.

    For AD7356 ADC i’m using AD8138 differential OpAmp (by referring the AD7356 evaluation board schematics and ad7356 datasheet).

    I made a pcb to check the ADC, when i measure the output pin of AD8138, it shows +4V and -4V at OUT+ & OUT- pins.

    The…

  • 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…

  • 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
