fast'n'cheap opamp LM318

gabbagabi

i went through all opamps on offer @tayda and found the LM318N.

He is quite fast with a slew rate of 50V/µs, on a reasonable pricetag,
i guess our beloved TL071 has something like 12V/µs.

So, if you did not before (like me), now u know him also Smile

My question is: do u know other fast'n'cheap opamps?

cheers, bb, gabbagabi

There are some other fast OpAmps with mixed specs but none beats the LM318 in price vs performance ratio:

- LF357 is fast (50V/us) but compensated for Av>=5,
- MC34083 is fast (50V/us) but compensated for Av>=2 (I bought bunch of them even cheaper than TL072),
- HA7-2525-5 (120v/us) other specs close to LM318 (still available locally for about one dollar/piece). Compensated for Av>=3.

Notice that LF357 and MC34083 (dual) are fast JFET OpAmps what is rather rare combination.
