OpAmp (virtual) Testing LM324 LT1012 LT1122

it looks like the LT1122 goes better for Amplifier-X testing than my prev. preference '1012
and here if why ::
LT1012LT1122





no much difference until here
"we" had to compensate the .CiR model ('s why i preffer the macro 1-s)

! The LT1122 can still handle the mess ?
(supposedly thanks to "fast output settling"? and/or 14x higher band with)

many attempts to reduce output offset (to Zero adj. the Amp.) - or - what was tested ::




the 1-st modification - G ( IS = 3.66mA )

the 2-nd modification - H ( IS= 813µA )

the 3-rd modification - J ( IS = 3.66mA )

onsemi source ( IS = 1.2(3) mA : VS = ±2.5(±15) V : RL = ∞ )

update 2017-09-19
verifying LM324 CLM-s´ variants ....


.... so the operation of G and J ver.-s is somewhat predictable.
