Hi,

I would like to know besides parametric differences between PCM1802 and PCM1803A, what are the other features that differs between both converters

    Hi, Lee,

    I'm not sure I follow your question... Can you clarify?

    Hello Lee,

    PCM1802 offers 105dB Dynamic Range with -96dB THD

    PCM1803 offers 103dB Dynamic Range with -95dB THD

    PCM1802 also includes the analog anti aliasing filter down to 300kHz, which is a significant advantage. (and is costly to add in silicon). The PCM1803 relies on a higher frequency anti aliasing circuit internally (therefor smaller), and the user should add an external filter.

    Is that enough to get started?
