• LTC6268-10

    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.

  • LTC6268-10芯片

    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, Shyam! My name is Mikalay and I'm working on a design similar to yours.
    At the moment I'm studying how the input overdrive of LTC6268-10 can affect the stability of the LTC6268-10 and the output signal from the LTC6268-10.
    My idea is to use…

  • Pspice for LTC6268 and LTC6269-10

    Hello,

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

    as I would like to simulate in other software.

    Thank you

  • 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…

  • 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…

  • 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…

  • LTC 6268-10 The bandwidth seems to be different from the datasheet.

    Hi

    I turned to Bandwidth simulation in LTSPICE to use the LTC6268-10, but the result was different from the datasheet.

    We want to implement a circuit with a bandwidth of 100MHz or more in the form of a transimpedance amplifier.

    The LTC6268-10 datasheet…

  • RE: High-bandwidth amplifier for avalanche diode

    Hi kazspore:  If the APD has fairly low capacitance, then the LTC6268-10 can be used in applications up to about 400MHz.

    We also have dedicated TIA's such as HMC799, with a 1GHz data rate, but the gain is 10k Ohms.
