Hi Emman-san,

Thank you for the confirmation.

The customer has temperature issue with AD8056. AD8056 seems very hot than they expected.

That's why they want to know the theta jc.

Hello Jonathan,

Thanks for your answers. What I means is:

1. Can AD8056 drive the AD9218? I only have AD8056.

2. Should I add the 15 pF capacitor between Ain and Ain-bar to AD8056 circuit if 1. is allowed?

Hi Anna,

Thank you for the information.

Yes, I am using composite analogue video. I have been trying to minimize the

cumulative gain and phase errors through the complete system video path. I

notice that the AD8132 video differential phase error…

网友提问：

谢谢您提供的信息。

是的，我在使用复合模拟视频。我一直在尝试最大程度降低

完整系统视频路径上的累积增益和相位误差。我

注意到AD8132视频差分相位误差与系统中

的其他元件（例如AD8056）相比高很多。或许我会

考察其他类似的放大器，因为我希望ADC驱动器

与AD8056的增益和相位误差类似（即，分别为大约0.01%

和0.02度）。

我希望应用工程师能够推荐

AD8138的其他替代产品。

谨致问候

Hi Kou,

Thank you for giving additional information about your application. I believe that in video switching, you should use an amplifier that has high input impedance, high bandwidth and high output current drive. With this specification, I recommend…

Hi Marisol,

Thank you for your interest in AD8056ANZ. There's an available SPICE model on the AD8056 product page. The SPICE model is in the format .cir, which should work in PSPICE. To convert it to .lib, open the file in a text editor, then simply…
