Hi guys,

Im kind of new to circuit design and was wondering if someo could point me in the right direction.

Im looking for two user friendly chips.

A Analog to digital converter 2^8 bit accuracy with a sign bit (for + and -) for the most significant bit.

No, I misunderstood your post and my reply was incorrect so I deleted my post, not yours.

Need more info. What is the required sample frequency, power supply, and input signal voltage of your A/D?
