Part Number: PCM5100A
Other Parts Discussed in Thread: PCM5102, PCM5100

Hi team,

My customer is facing supply situation on PCM5100APWR.

Could you please check if PCM5100APWR can be replaced by PCM5102PWR? And are PCM510xA and PCM510x devices only different in voltage logic whether it supports 3.3V only or both 1.8V and 3.3V?

Best regards,

Jay

These TI DACs have an SNR (typical) of 100dB (PCM5100) and 112dB (PCM5102), so replacing a lower SNR part with the higher values should be perfectly okay.

For the difference between A and non A version please refer to:

Hi Arash,

So PCM5100APWR can be Pin to Pin replaced unless the customer is using 1.8V right?. Got it! Thank you so much!
