Part Number: PCM1861

Hello,

Currently I use the below circuit for receiving  audio inputs to PCM1861

There is also  a voltage scaler before the above circuit.

Can you please guide me for improvements to the input circuitry?

thanks

    Hi, Rifo,

    The PCM1861 is a flexible device which input stage can support several configurations as long as the voltage on the input pins is under the specifications from the datasheet. The circuit you are currently using seems fine, I don't think a lot of improvement is necessary for general applications.
