    hi guys,

    I want to know about 'minimum external voltage references' that can be given to ADC.suppose i give external voltage references as " 0 V and 3.3 V " then a step size would be ( 3.3/1023 ) V rit????

    thanks ........

    No the step size will be 3.3/(2^n). There n is number of bits. So in this case the step size is 3.3/1024
