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?
I am not sure about the JFET and TIA, but you need to pay much attention about the consistency of the 2 photodiodes when designing balanced detector. the balanced detector is used a lot in interferometer receivers that the 2 PDs will cancel out the DC…
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:…
Is there a Pspice model for this component LTC6268 and LTC6269-10,
as I would like to simulate in other software.
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…
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…
I am attempting to reset the capacitor of an integrator circuit by shutting down the chip (driving pin 8 with a 4 usec low-active pulse) and pulling the output down with a 10K resistor (capacitor is 3.3 pF). Discharge of the capacitor should occur through…
I test my TIA circuit.The scheme of LTC6268 is as follow:
And the waveform is like this.
By adjusting the feedback resistance and feedback capacitance. The oscillation cannot be lowered.Can you help me to eliminate the oscillations?
