Hi Diego/TI

Is there a way to determine what is the input referred noise for the PCM1865 for single ended and differential inputs, relative to the PGA gain?

Thanks

For example, ff the Analog PGA gain is set to 10 , 11 or 12 dB what will the input referred noise be for single ended and differential inputs?

Thanks

Hello,

Sorry for the delayed response. We have found some data that was captured a couple years back during the initial development of the device, hence we were able to estimate a plot for the input Referred noise Vs PGA gain of the PCM1865.
