I have a few questions about the pin purposes on the TLC7135C 4-1/2 digit precision analog to digital converter. Can someone please explain the purpose of the following pins and state if they are mandatory or not:
and I was also wondering, do the -cref and the -in have to be the inverted values of the + pins (like 2.7 V becomes -2.7 V)? and if so, can I just use any op amp (like the LM339)?
Thank you in advance!
Welcome to the e2e forum! The TLC7135 is a unique device and I'd like to know what sort of application you are using it for. All of the pins of the TLC7135 have functionality. The over/under range outputs are not necessarily 'manditory', but you can't ignore the other pins...
For the TLC7135, i plan to have it take analog input to save pins and output to a BCD to 7 segment display IC.
One other question, can DGTL GND be linked to GND on an arduino or does it need something else?
Also, if busy is an input, does it halt when it goes high or just holds the data until it goes low?
DGTL GND can be tied back to GND on your controller. The BUSY signal is an output, so I'm not sure I follow your question.
