PCM5102A: VCOM and VREF mode explanation needed

Part Number: PCM5102A
Other Parts Discussed in Thread: PCM5122,

What are the differences between the VCOM and VREF modes, and how are these modes determined? The datasheet specifies a different voltage range for each of these modes.

    Hi Jatan,

    This is actually a holdover from the PCM5122 device, which is very similar. The PCM5102A is a smaller device and does not have I2C access and VREF/VCOM mode available. The PCM5122 datasheet describes the differences between the VCOM and VREF mode - but, the PCM5102A only supports the VREF mode, so really that is the only item that should be listed in the table. I will notify the systems team to see if we can remove that from the table.

    Thanks for the good catch!
