I am still studing OP-AMPS and I was playing around with voltage follower/buffer configuration, the very basic diagram connecting the inverting input to the output directly and put some voltage on the non-inverting input
I supplied the op-amp with 11.1 volts
what I have notice that it was working as expected with TL092 and LM741, the output voltage was following the input voltage but when I tried LM393 or LM339 it didn't work as expected actually the output voltage totally became irrelevant for example if I apply 5 volts on the input, the output measures .9 volts or something around that value
if I apply vcc on the input I get just 1.308 volts
can someone explain why is this happening?
