  • Forum Post: PCM1792(A) - Various Questions

    Jens Bauer
    Hi, I'm a 'newbie' in this area; currently developing hardware for (and software to control) a PCM1792A. A few questions arose in my mind. 1: Why is the DSD schematic different from the PCM schematic ? - isn't DSD just an input format? 2: What's the max. available sampling...

    Jens Bauer
    I agree as well. The S/N virtually eats up the extra 8 bits, but if using two DACs in monoaural mode, one could get a little closer. My guess is that the cool dudes behind the DACs are most likely working on something awesome right now. If not, I'd suggest that they make an 'easy enhancement'...

    MKARGER
    Regarding the PCM4220 24-bit ADC, is there a minimum time that needs to be enforced between the time that power is applied to the ADCs and the time that RESET is deasserted and the 1024 MCKI initialization period begins, in order to allow the VCOM and VREF outputs to stabilize? We have an application...

    I hoping someone can help me locate an ADC that is capable of sampling stereo analog audio input and produce a 16-bit I2S bus output digital stream. I had been looking at using an ADC developed by Crystal/Cirrus Logic some years ago that is now obsolete. The CS5330 was a small 8pin packaged chip that...
