Hi,
It seems there is no simulation model for Pspice for LT6275. So, will the one in LTSpice work in Pspice? Or may ADI provide one for us, or some docs to port it to Pspice?
Thanks.
Unfortunately, we don't have a LT6275 spice model that is compatible with Pspice. The model of LT6275 is solely created for LTspice use only.
Just curious, why do you prefer to simulate it using Pspice wherein you can readily simulate it in LTspice which is free to download and easy to use?
I have a big simulation project in OrCAD Pspice already. I want to replace one OP Amp in it with LT6275. And I'm more familiar with PSpice.
Can you disclose a bit what particular application ckt or why did you select the LT6275? I could suggest a similar part from ADI portfolios which might have a spice model readily compatible with Pspice.
Gain flatness at least 1MHz when G = 10, with 20Vpp output swing. Votlage noise < 10n / sqrt(Hz)
Could you check ADA4637? drawback is not so low power, 7mA supply current compared to almost 2mA for LT6275.
G=10 is flat at 1MHz, supply voltage is up to 30V and output voltage is 25Vpp typical.
Slew rate is quite high at 170V/us but not on the range of LT6275 which is 2200V/us.
It seems, when G = 10, the bandwidth reduced to only 100KHz around. And when G = 10, may the large singal slew rate can achieve 170V/us too?
Have you look at Figure 41 in the datasheet? It is the image below
For slew rate, 170V/us is for G=5
