AD8603 gain-bandwidth product

And in one part I measured it was more like 722 kHz.

Hi marcelobaru ,

May I know how you measure the AD8603's GBP?
I won't be able to guarantee the min and max of AD8603's GBP.
But may we know the application and desired configuration (Gain, Bandwidth, etc.) for the AD8603? We may be able to help out further if we have this information.

Thank you.

Best Regards,
Dann

Hi Dann,

I measured in follower configuration with a common mode input voltage at 1.65 V and a power supply of 3.3 V.

Best,

Hi marcelobaru ,

Are you using an evaluation board on your test?
How accurate or clean is the common mode voltage, the amplitude, Rload, etc?

Need to know all the possible contributions to these difference in results you're getting because checking an old repository.
Looking at no Load condition, I haven't seen GBP exceed 450kHz and drop below 380kHz. but this is still a typical value and not guaranteed to be the min or max for the GBP spec. What's your target bandwidth if I may ask? thank you
