I am using a simple Op amp. I have a 1khz square signal. I have a non inverting op amp circuit. the in put signal is 0-3v while the output signal is 0.6-3 V.
the circuit has no feedback resistor and the output is directly connected to the negative input.
where this difference come from and how can I have the same output signal as my input.
The op amp is LT1819CMS8#PBF.
Thanks for helping.
