AD8692用AD8691的spice模型，AD8692是双运放，AD8691是单运放。

其他器件如果在LTspice中找不到，可以到ADI官网上下载相关spice模型（.cir文件），每一个运放的页面基本都能找到相关的spice模型（一般在Datasheet下面）。然后将cir文件导入到LTspice中自建电路模型。

I can't find them for AD8692 opamp and ADCMP608 comparator. No special footprints, I just wanted to double-check.

Hi Mika,

We currently don't have ADA4530-1 in a die level and I'm  not sure if we will have in the near near future. However, i found these few devices with 1pA typical bias current operational amplifiers in die/chipscale package. We have AD8691…

Elias,

  What does TRRS mean??

  What is your highest signal frequency?

  Depending on whether you need to go to DC or not and can AC couple, you could use op amps

that have millivolts of offset, rather than <100 uV which drives up the price.

  Also…

Hi firman,

Figure 12 is the phase shift between the AD2S1210 EXC and SIN pins which shows how the noise from EXC pins of AD2S1210 was improved.  This is because of the amplifiers which acts as an active filter found at the resolver excitation(which uses…

Thank you for a thorough explanation.

I have looked further at your catalog of op-amps. Since I am designing a portable unit, I examined the following, with 5 V supply:

AD8605/AD8606/AD8608, AD8691/AD8692/AD8694, AD8655/AD8656, and the ADA4075-2.

ADI放大器给我的印象就是产品丰富，可靠性高。

再说说如何选择不同的放大器。

（1）确定放大器的用途和应用场合：放大、滤波、积分、隔离，还是低频、高频、音频等。

（2）确定放大器的输入输出、电源、使用温度环境范围。电源分单电源和双电源。

（3）确定关键技术指标。比如滤波电路需要首先考虑放大器带宽，电荷放大电路首先考虑低失调电流等。

（4）根据PCB和产品尺寸，确定封装形式。

（5）结合产品手册选型。

实例：在设计一个传感器的调理电路时，需要用到放大器进行放大，信号频率不高<1MHz…
