PCM4104 reference circuit

Other Parts Discussed in Thread: TPA2017D2, PCM4104

Hi,

Is there any reference design which I can follow to connect PCM4104 to TPA2017D2   x 2?

    Hi, Lee,

    We don't have such a circuit. I would probably put an RC LPF between the two to knock out any out-of-band noise from the PCM4104 going to the TPA2017D2. Please see the section labeled, "OPERATION WITH DACS AND CODECS" on page 12 of the d/s. Essentially you want this to be about 30 kHz cut-off and use resistance that optimizes between noise and gain error in the TPA2017D2.
