TINA-TI: Can TINA-TI simulate the phase difference?

Other Parts Discussed in Thread: OPA858

Hi team,

I have a simple question about TINA-TI.

I am trying to use OPA858 and would like to simulate the phase difference.

Are there any way to calculate it by using TINA-TI?

If it's possible, where should I go to learn about it? 

Best regards,

    Hi Yuto,

    Good question. Yes, TINA-TI does simulate phase delay. It is closely related to the bandwidth; a high frequency near the bandwidth limit of the amplifier will have more phase delay than a lower frequency. Here is an example using the OPA858 in +10V/V of gain (~900MHz of bandwidth). An 800MHz signal has phase delay and reduced amplitude, but a 100MHz signal does not.
