Rail-to-rail op amps at Tayda?

[electrosonic]

Putting an order there and could use a rail to rail op amp for a current source I am building. Its a pain to search through all the data sheets, any one know one they sell?

Thanks.

TLC2272?

[electrosonic]

That should work - thanks!

Also 358.

I think the LM358 includes the negative rail but not the positive rail. I am making a current source out of "The Art of Electronics, which need an opamp that can swing to the positive rail.

Head over to Texas Instruments and you can order samples for free...

Ah! thanks. I used it in a project that needed to swing negative; didn't occur to me to check if the positive rail was used.

What samples would you recommend asking for? Hardly seems worth the effort for jellybean ICs, however those are what I am familiar with.

at ti, get some the "lmc648x" series opamps, single dual quad cmos.

Jeez, too many to memorise! Off the top of my head, TLC2272, LM6132. Use their parametric search.

Don't forget, there are some op amps that are rail-to-rail at the input but not the output and some are rail-to-rail at the output but not the input.  Read the specs for input signal range or output signal range from the datasheet to determine what you have.  Also, determine what the design needs.  Then you can choose.
