I90 B. Operational Amplifiers with Nonstandard Pinouts

Now, it is true that I have only listed NSC parts in here. Maybe someday we will
list all the parts in the world, but I haven’t the time to do that now. I’ll leave enough
space for you to put your notes alongside these for the sake of completeness. (Note,
in no case can I vouch for which direction you turn the pot to increase Vas. That’s for
you to determine.)

Notes On Dual Amplifiers.
All DUAL operational amplifiers in 8-lead TO-99 packages (often called “8-lead
TO-5”) or 8-pin mini-dip or SO-8-all have the same pinout, as far as I have ever
seen. Examples are: LM158, LM833, LM1558, LM6218, LF412, LF442, LF453,
LMC662, LPC662, etc., etc. There are no exceptions that I know of-tell me if I am
wrong-in this field. (The old dual LM747 in its 10-pin package, or the dual LM709
in 14-pin packages or any dual in any package with more than 8 pins-they do not
count.)

Notes on Quad Amplifiers.

All quad operational amplifiers in 14-pin DIP packages all have the same pinout,
EXCEPT FOR THE LM4 136! !
The standard ones include:
LM124LM324, LP324, LM349, LM837, LF347, LF444, LMC660, LPC660, etc.
There are very few exceptions in this field. (Note-Quad comparators such as
LM339 do not have the same pins as quad op amps. Even the power supplies are
different. Quad Norton amplifiers such as LM2900 are also nonstandard.)
