How to set up an analog to digital converter like parallel TLC0820AC, to convert input voltage (volts and tenths) into a BCD?
The problem is that there are lots of codes output by the ADC that aren't valid BCD because they're the hex numbers A-F.
The normal solution is &quot;use a microcontroller&quot;, but I think there might be some binary-to-BCD or analogue-to-display converter chips in the 74LS catalogue?
