LM324 push/pull ckt?

[Robert Martin]

Can anyone recommend a schematic for a push/pull, or "dual drive",
type amplifier (unity gain) based on 2 amps of an LM324 that will
drive a 2K resistive load?

Input is 5V audio. Supply is 6V.

Couldn't find anything specific via search.

Thank you,

Robert M.

Hi Robert ..,

Do you want to amplify an audio signal ... !

If yes, you can use only one op-amp, and the gain cannot the 1.2 ..
becuause if exceed the 1.2 gain, the output signal will saturate ...

Firstly, I think you probably mean a differential or 'balanced' output.

Input is 5V audio.

5V rms ? 5V pk-pk ? 5V pk ?

Supply is 6V.

You'll get sod all voltage swing out of an LM324 running on a single 6V
supply !

Why a shitty LM324 ? Why 6 Volts ?

Couldn't find anything specific via search.

Probably because it would be expected that anyone wishing to do anything
so basic would have a clue to begin with ?

First off you need to explain what you require accurately and concisely.
If you can't do that you're probably better off forgetting it !

yep, lm324, ugh.
if its for audio try AD's ssm2142 diff line driver

Serious error.
All shortcuts have disappeared.
Screen. Mind. Both are blank.

While seconding the above, if you're going to have to try something
(you're on a desert island with an internet link, a tube of LM324s and a
bunch of passive components), you might as well try this (view in fixed
font or M$ Notepad):

That's an LM324. Doesn't it need 5.6 kohms from each output to ground to
prevent crossover distortion?

Sorry, Mr. Popelish. The cruddy AOL newsreader has finally caught up with the
thread, and I see I stepped over your input. I guess I'm too cheap to
subscribe to a store-bought real newsreader. (;-)

Xnews and Xananews, among others, are freeware and quite good. Get
