I would like to build a ADC to use it in a line follower robot, this ADC must be 8 bits. This ADC going to be connected to a microcontroller, for example the DS89C420, I would like someone to indicate me some online documentation, or other stuff, that could help me initiate the working and designing of ADC's. Like the one described above.
hi u can use avr series micro to use adc since the resolution is about 10 bits and u can set ADLAR bit to get ur result in 8 bit either in ADCH or ADCL...its quite simple......al the best....just read ADC section in datasheet of any atmega series of micro.... it is the easiest way of implementing adc...
If u use PIC micro controller PIC 16f877a... U need not to use seperate ADC.. PIC contains inbuilt ADC u can directly connect IR Input to the PIC . Analog inputs PORT A............
Added after 30 minutes:
k other wise u can go for ADC0804 for ur A/D conversion...
if ur microcontroller not conain inbuilt ADC...so u can interface this ADC with ur Micro controler
