Hi Alex,

PSoC3 and PSoC5lp has same circuit for op-amp. So they have the same specs for op-amp.

Thanks

Hi VSRS

Thank you so much for you answer .

What you say is right for  en ( input noise density).

Avol =90 is at page 9 of data sheet at it belong to PSoC3  info.

So I am wondering if the same value  is the valid one for both vesion of PSoC.

At page 13 start the DC and AC characteristics for PSoC 5LP and ithere is no mention to AVOL.

Again, thank you very much

Berst regards,

Alex

Thank you Roy !

Anyway the spec sheet is a little bit confusing because there are  the same info for both devices with different values.

For example you have SR and GBW   with different  values,

I am wondering which are the GBW for the different power modes for the case of PSoC 5LP.

Any way thank you very much for your answer.

Hi Alex,

The opamp need update for PSoC 5LP Characteristic, will be done in the future version of the document.

Alternatively, you can look at the PSoC 5LP device datasheet http://www.cypress.com/file/45906/download  for Opamp DC/AC Specifications.

Thanks

Roy
