图3是对图2的输出波形进行放大，图2波形相对于图1只是更换了输入信号源，滤波电路设置Cav为10uf容值，然后输出波形交流分量变得很大。

• ### RE: Calculation formula for settling time AD736's

Hello Emman,

Just I would like to know as following.

I am confirming your Fig.8 on AN-268 page6/12.

It show at CF=0uF condition.

So I have a question, if CF become large value eg.1uF,10uF,,,,, how does CAV-line move to?

I need the its characterristic…

• ### RE: AD737 scale factor and linerity

Hi George,

I also want to verify the schematic of your customer. Are you referring to the Figure 29: External Scale factor Trim or Figure 30: dB Output Connection?  Also where the 22 ohms was inserted, between the -Vs(Pin 4) to Cav or Pin 4 to ground…

建议你试一下数据手册中图8或图11的电路。在数据手册中介绍了一些关于Trim的方法。还有就是电容值的计算。你可以根据那个算一下你选的Cav是否合适。

• ### RE: Differential voltage 0 to 300 milli Volts across a shunt

Hi Klaus,

I Got PCB done with AD636, It is working fine, But the response time is bit slow and I think that can be adjusted with Cav()C3 capacitor by lower it.

I need to check AD736 as well I think It should also work with the same circuit I have Uploaded…

1. 输入1V正弦波，输出要建立到0.99V，也就是1%精度是需要时间的，就是纵轴。

2. 1ms的转换时间很短，参考Figure13，你需要小的CAV，比如10nF，此时20kHz的信号建立到0.01%误差需要，10mS。建立到0.1%的误差，可能为1ms。

The device will handle formats up to 720p/1080i with output of YCrCb 20 bits which fulfills some of the BT.1020 specifications.  The ADV7181C LLC is limited to 110MHz so it can not output 1080p60
