I used a PIC16C55/57 as an 8-bit comparator. 8-position DIP switch tied to port C
with appropriate pullup resistors, and the 8 address bits to port B. The software
compares the two, and when they are equal, it outputs a pulse from port A. I
have a STROBE bit tied to one pin on port A, so it only...
A superconductor!
But seriously, I use them in places where I have a spot on a circuit
board, and, due to a reconfiguration, I need a short instead. They
are also used when a design might be changed in production. If
your autoinsert machine is already set up for placing chip resistors,
then it's...
I glanced at the data sheets, and noticed that the common mode range is quite
different between the two parts.
The OPA2277 specifies (V+)-2V to (V-)+2V
The LT1013 specifies (V+)-1.5V to (V-)
If something in your circuit puts a voltage outside the range on the inputs,
no telling what exactly...
