#120452 - Help with ADC0838/ADC0808
In my project, there is a need for me to utilize the AD converter to convert analogue sensors to digital form and used by 8051. After some research i have finally found the AD converter that i needed but i need to make a choice between a Serial output and Parallel output ADC. With a note that i am trying to conserve as much ports pin as possible, my question here is :

1. Which model should i pick? The ADC0838 (Serial Output) or the ADC 0808 (Parallel Output) and why? Is there any pros and cons to each of them? Please let me know!

2. I have tried to search for a algorithm/code to retreive the code in a serial bit stream from AD converter for a long time now (assuming that i am using the serial output) but i have yet to find any. can someone point to me the code sample or simply hints on how to get started (multiplex the ADC & retrieve the digitized output). I am using C language to program for my project and i have absolutely no idea what to start with.

that's all i need to know for now. thank you very much in advance for helping!

   Serial or parallel.            01/01/70 00:00      
   It\'s dependent on your timing constraints            01/01/70 00:00
