My ADC0809 is to be used as standalone only taking input from one channel....ALE,OE is kept high....EOC and SOC are connected....we used clock from external scmhitt trigger as colck with freq 800KHz...start is given by a switch....LED's(connected after 120ohm resistance)glow randomly.
I had successfully operated it with internal clock and NO start pulse...SOC was always kept high....but it only came good one day and from the very next day it doesn't work.Please help
