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.
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…
Is there a Pspice model for this component LTC6268 and LTC6269-10,
as I would like to simulate in other software.
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…
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…
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…
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…
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.
