Dear sir,
I am working with audio daughter card ak4588v0 with ompl137,in that i found RCA Didgital in and Digital out.My questionis that,
what is the Digital in....? means data is taking by means of 0's and 1's.....if so, can we provide mobile songs as input(by using converter sterio to RCA) to Digital in of RCA connection...?
If am right then what is the difference in giving the input to ADC IN(analog) and RCA IN (Digital)..?both are taking mobile data(analog signal).
what is the need of PCM1802 ADCs, as we are having AK4588 combo Codec (DIR & 8ch DAC),which does the operation of ADC and DAC...?
what is the use of LM337 voltage regulator.(ouptu −1.2 V and −37 V)..?will it require negetive voltage..?and we have two numbers....why we need 2..?
thank you
