Dear sir,
Kindly help for following problem :
I am reading dc voltage at on-chip adc i/p of PIC 18F6585 microcontroller thro MUX (part no : HEF4067).But Observed considerable voltage drop at MUX o/p.Hence adc reading corrupted.
MUX VCC : 5V
Micro VCC : 5V
DC voltage(i/p to LM324 based ckt) : 2 - 15 V
What could be the reason?
What would be the steps to troubleshoot this problem ??
Reagards,
