ADA4528 for audio application with low latency

I have found that ADA4528 have good characteristic for low latency audio application but I'm wondering why it's datasheet doesent mention audio application in its application part.

Main Problem is that ADA4528 have high settling time compared to fast OpAmps as much as 10us.

Now Question rises that really does this settling time contribute to delay of OpAmp (because I need cancel the noise and need critical timing, I think only frew ns of delay is acceptable).

And will this make constraint on ADC sample rate and resolution? HOW?

    Hi,

    The ADA4528 amplifier belongs to the zero-drift amplifier portfolio. The reason it has a high settling time compared to other op amps is because this amplifier specializes in precision, and low-frequency application such as: pressure sensors, thermocouples, and etc.

    The ADC driver, would depend on what ADC you're going to use. You could try out the ADC Driver Tool to test out different amplifier and ADC combination that would suite your needs.

    Thanks,

    Donnie
