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:
REF
ANLG common
int out
auto zero
buff out
under range
over range
dgtl gnd
busy
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!
