Ok so after that i decided to take a look on these IC's:
TLC1549CP as 10-Bit Analog-to-Digital
TLC5615CP as 10-Bit Digital-to-Analog
I don't understand anything about these IC's they are new to me, are they good for the work i'm thinking on doing with them?
If i need more quality then i would think on a better converters, this is just for practice but i would love to put this on working before buying anything more expensive.
