PCM1822: Single Ended Line-Input

FXtreme Electronics

Part Number: PCM1822
Other Parts Discussed in Thread: PCM1821, PCM1861

Hi:)

Does the PCM1822/PCM1821 support Single-Ended stereo Line-Inputs for standard auxiliary audio, or would the PCM1861 be a better fit for this?

Also, are any circuit diagrams available for the PCM1822/PCM1821 and Single-Ended Line-Inputs?

Thanks!

I would suggest to use PCM1822 .

This is a snapshot from the evaluation module This has a schematic

Thanks for your reply.

Thanks, this helps! I see however that the PCM1822 only has 1Vrms Single-Ended input while the PCM1861 has 2.1Vrms Single-Ended, Doesn't this mean the PCM1861 would be better suited for this application (3.5mm aux) or should the PCM1822 still be a better choice?

Thanks!

To my opinion the PCM1822 is a newer part.

It also has DRE that can get higher SNR
