Hi Team

We design a audio system use PCM4201+DSP+PCM5102A, but we can't get the right date from PCM5102A. We have some question need to confirm. thank you

1. Can PCM4201 support standard I2S output?

2. PCM4201 is a single channal A/D, the output is R or L audio singal ?

3. Is below schematic anything wrong ?

Hello,

PCM4201 supports, LJ/DSP serial audio configurations.

Can you probe the analog inputs to the PCM4201 devices? Based on the single-supply power configuration applied to the driver amplifiers you're going to be clipping out 1/2 of our input waveforms to the PCM4201. Can you probe the analog input pins directly of the PCM4201?

PCM4201 is a single-channel differential input ADC, so you can input either the R or L inputs to the device. You'll need a second PCM4201 or a PCM4202 to support stereo inputs.

Hello Colin

When I input L or R signal to PCM4201, the output is L or R ? Can we identify from the LRCLK ?
