Hello all,
I want to design a 30MHz clock buffer using the LTC6252/3/4. the input is actually a clipped sine wave TCXO with 0.8V amplitude.
I don't have many experience in designing with opamps, so I used LTspice.
The design look like this (Singe 3V…
Hi,
With LT6233-10 GBW=320MHz, 2MHz bandwidth is not attainable with a gain of 200. 320MHz/200 is 1.6MHz. The gain-bandwidth product is the product of the closed-loop gain and the 3db closed-loop bandwidth at that gain. Increasing the gain, directly…
Hi,
I want to convert single - ended input to differential ended for driving ADC. I have gone through datasheet of ADA4940-1 in which calculations are given to terminate single ended input. For known source impedance I am using LTC6252 as buffer. But…
Hello,
Attached is a design from the photodiode wizard tool. It is a two stage design. When second stage is non-inverting, -3dB bandwidth from the tool (fN) roughly matches with that from LTspice. However, when the second state is inverting, the tool…
Hi Arthur: We always had only Alloy-42 or Copper lead frames. I don't know which lead frames (or pads if applicable) are available under LTC6252/3/4. Is Alloy-42 or Copper non-magnetic enough?

Hey Walt
Thank you for your reply, book and tutorials. currently I am doing a university project, we created a sensor for sensing the sound wave, but current out signal from sensor is very sensitive to noise. I need to choose a Low noise amplifier.
…Hello,
I am trying to design a circuit to achieve a gain of 10 for input signals up to 50MHz. I have looked at LTC6253 as a possibility, since it has quite a large GBP of 720MHz. If my understanding is correct, for a gain of 10, it should handle up to…
