Hi team,

I would like to use LTSPICE software to simulate LTC6268. But I do not know how to use the LTSPICE software. Would you send me some documents and

some videos that can teach me how to use it?

请教一个运放自激问题。电路是一个交流跨阻放大器，运放使用LTC6268-10，单电源3.3V供电。采用电阻分压+跟随器生成中心参考电压。PIN的结电容是2pf，电路设计带宽是60MHz。但是测试时发现输出有9.5MHz左右的自激，想请教一下是电路设计问题？还是布线布局、寄生电容的原因？

其中C5电容设计值是0.1pf，手头没有这种电容，所以实际测试时是开路，希望利用寄生电容来产生0.1pf。C5用1pf时没有自激，但是带宽不够。

R3用过0R电阻，同样有自激。

Hello,

In order to reduce noise, i use a JFET BF862 before the amplifier ltc6268-10,but i find a large offset current in oscilloscope. I want to know how solve it.

Hello,

For a research project I am working on I need to use the LTC6268-10 op-amp. In my project I need to reduce the parasitic capacitance as much as possible. As a result, I am trying to get bare-die of this op-amp and directly wirebond it to another…

We would like to use the LTC6268 or LTC6268-10 for a charge-sensitive amplifier application, essentially an integrator with a large resistor in parallel with the feedback cap.

The input signal is an approximately 100ns wide pulse of 10s to 100s of femtocoulombs…

             I currently work in using trans-Impedance amplifier to detect current signal. But the transfer function H(s)  I deduce is different from what in datasheet. I wonder how to obtain the formula the same as the form in the datasheet. Thank you. https:…

在LTC6268-10芯片手册中，为了减小寄生反馈电容的影响，采用反馈电阻分流的方式减小寄生电容。

请问，在这种工作方式下，为了使寄生电容降到最低，对电路板的材料类型和厚度有什么要求吗？

Hi,

The graph provided for LTC6268 input bias current vs. temperature does not allow me to see values at temperatures below 50C. Is there a table I can get with the values shown in this graph? I need low bias current, but only up to 45 or 50C and the…

Hello,

Is there a Pspice model for this  component LTC6268 and LTC6269-10,

as I would like to simulate in other software.

Thank you

Hi,

Iı am new in this forum. It is very nice to be able to ask questions. Thank you in advance. 

I bought LTC6268-10 for a trans-impedance amplifier application for LIDAR. The laser emits in 10ns pulse and bandwidth of the laser is 1 khz. I have chosen…
