hi guys,
i intend to use the ADC0804 IC as the ADC for my uni project. the datasheet says it can operate in a standalone mode. i've cr8ed a standalone circuit with LEDs to show the output. however, my circuit seems moody. sometimes it works sometimes it doesn't. i followed the diagram given but i left the digital ground out. furthermore, connecting digital ground to the supply ground does not solve my problem. any ideas?
ps: i'm trying to get it to work before interfacing it with the microprocessor
