• Is ADA4851 a little slow to drive 40MHz ref in clock on AD9361?

     

    The user guide for the AD9361 suggests using the ADA4851 op-amp to buffer the 1.3Vpp reference clock at 40MHz when used for baseband synchronization purposes. Looking at the datasheet for that part, figure 26 suggests that it has a ~150V/us slew rate…

  • ADA4851-4带通滤波电路,自激振荡波形怎么消除?

    ADI网站上的滤波器设计向导,我在里面设计了一个200K的带通滤波电路,参数设置和最后得到的电路图如下,运放没用LT6233,用的是ADA4851-4。

    但是在做好板子以后,输入端用信号源输入了一个200K的正弦波(下图蓝色波形),在电路图中阶段D的输出(U2D输出)测到的波形如图中黄色部分,这是电路被输入的波导致振荡的缘故吧?该怎么消除?还是说这是板子的原因,跟电路图没什么关系?

    在整个电路的最后输出地方(U2A)得到的波形如下图,蓝色的波形是输入,黄色的的波形是输出。

  • AD9523-1  Can I precisely adjust output clock frequency with AD9523-1 (EVAL-AD9523-1)?

    Greetings!

    I would like to inquire if it is possible to achieve precise frequency control with EVALZ - AD9531-1? I'm interested in generating a clock signal that is a multiple of femtosecond laser output pulse rate, which can be something close to 80…

  • ADATE305 VDDO_0/1, VSSO_0/1 termination

    Hello,

    In case that VDDO_0 (pin 83), VDDO_1 (pin 93), VSSO_0 (pin 81) and VSSO_1 (pin 95) is unused, what termination is required?

  • HMC666_using IF pin without 1:1 transformer

    Hello Team.

    1:1 transformer applied in IF pin is expensive.

    so we want to use without transformer.

    is it possible that?

    Can you support solutions?

    thanks.

    Best regards,

  • Composite amplifier using ADA4637-1 and ADA4870-1

    I want to build a composite amplifier using the Figure 77 of the datasheet ADA4870-1. It says that the voltage offset is less than 500 uV. I simulate this circuit using LTSpice, when driving ada4637-1 with 0V and monitor the output of ADA4870-1, it is…

  • ADA4627-1 and ADA4637-1 Null Inputs Connection

    Hi,

    ADA4627-1 and ADA4637-1 have NULL pins which are offset adjust pins. If I do not plan to use offset adjust what should I do with the NULL pins? Leave it floating or use 100k Ohm pull-up resistors?

    Regards,

    Ivan.
