• LTC6268-10 1khz bandwith application


    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…

  • LTC6268-10: Input Capacitance & Input Bias Current in LTspice


    I couldn't find any answer to two questions regarding Analog's/LT's models in LTspice in general and the model of LTC6268(-10) in particular.

    • Do op amp models already include input capacitance (0.1pF resp 0.45pF for LTC6268-10)?

  • LTC6268-10 PCB铺铜

    你好,我设计的20MHz光电转换电路的pcb布局如截图所示,使用的运放是LTC6268-10,根据datasheet的描述,需要在输入端口增加模拟地保护环以及“Other signals should be routed well away from this signal path and there should be no internal power planes under it”,这段英文的含义我不是很清楚,它是指将和芯片的同相输入和反向输入端焊盘下的铜皮掏空,以及将与输入节点相连的所有的电阻焊盘下的铜皮都掏空吗…

  • LTC6268-10 feedback capacitance mitigation with single supply


    I'm designing a transimpedance amplifier based on LTC6268-10 amplifier.
    I read through the documentation and I saw the DC2414A design files, so I understand that to lower the parasitic capacitance of the feedback resistor placing a ground trace…

  • LTC6268-10


    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.

  • LTC6268-10 propagation delay time

    Hi engineers:

    I use the LTC6268-10 as Photomultiplier Tube Post-Amplifier.The scheme as follows.

    Example waveform from LTC6268-10 datasheet.

    What is the delay between input and output?I test it about 10ns,is it right?Is there a nominal value?Thank you…

  • RE: LTC6268-10 output oscillating


    Apologies for the late response. I could not respond to your message due to some errors.

    Given the specifications, Ipeak=100uA, Vo=1.5Vpp. and APD parameters, LTC6268-10 would be a very good choice. To achieve a 1.5Vpp output, we would need the f…

  • Coupling of LTC6268-10 and AD8336

    Dear Enigeer!

       My purpose is to amplify the current signal generated by APD into a voltage signal through a two-stage amplifier. The first stage amplifier is going to use ltc6268-10 to amplify the current signal into a voltage signal, and the second stage…

  • LTC6268-10 output oscillating

    Hi engineer :

     The scheme is as follows:

    Then I test the J11 signal.The J10 is not connect anything.

    But the waveform is like this.What are wrong.The input or the power?

    Then can I use LT3092 to test the TIA circuit.

    Connect J3 to TIA's J10.Looking…
