LM324: Single Op-Amp Version

Part Number: LM324

Is there an IC made that has the same circuit as the LM234/358 op-amp circuit only there is only one on the IC and it possibly would have offset adjustment?

Hi Andy,

Unfortunately no, we do not offer a single channel version of the LM258. We do have a number of single channel devices though, can you describe what you need for your application? I'd be happy to help you look for a suitable replacement.

Best,
Paul

Hi Andy,

I wanted to correct my previous post - the single channel version of the LM358 is the LM321. It does not have offset adjustment however. If you can provide more details on your application, I'd be happy to help recommend an op amp which fits your needs.

Andy,

TS321 is the single version of LM324 or LM358. LM321 is the single version of LM324-N or LM358-N
These facts are not obvious therefore, Paul did not know this.

My application is a simple photodiode amplifier adapter for an old film camera; Its output needs to be 0-5V for no light to full sunlight; I would like to use the LM324 type because it is battery powered (therefore single polarity) but I like to have as few op amps in something to save on supply current, thus the reason for the LM321 rather than LM324/358.

Andy,

TLV27L1 could be a good choice due to its wide VCC range 2.7V to 16V, low supply and input bias current. It is much slower however.
