Hi Team,

I can’t find Phase vs Frequency of Figure11.

Could you please let us know if you have any information(graph)?

Regards,

Hi Hide,

a phase is usually only given in the open loop gain figure. See figure 10 of datasheet.

But you can easily find the phase for the closed loop gain when running a TINA-TI simulation.

Hi Kai-san,

Thank you for your prompt reply.

I understand that "Phase and Frequency of Figure11" is typo.

Is my understanding corrcet?

Regards,

Hello Hide,

Yes, it appears that the words "and phase" should have not been included in the Figure 11 title. We will make note of that datasheet error.

The closed-loop gain/phase response can be closely approximated for a particular circuit from a TINA-TI simulation as Kai indicated.
