Check out the LMC6032/LMC6034 or LM6132/LM6134. The data sheets and
free samples are available at "www.national.com/design". The final
device choice will depend on your cost/performance criteria.

Hi!
—
I need an op-amp with these qualifications:
less than 5V (+-2.5V) power supply
temperature range from -40 to 85 C
two or four in one package
cheap
Any suggestions?

How about the automotive version of the ordinary LM324, called the
LM2902? It will work down to less than 5 Volts, and is guaranteed for
the exact temperature range you want. It is also dirt-cheap (about
$0.50 each), and is naturally (being an LM324 derivitive) a quad opamp.
This is the standard generic opamp used in automotive electronics.
The LM2904 is the same thing, but is only a dual opamp (in an 8 pin
package). That is, it is an LM358 that is guaranteed over the full
automotive temperature range. Both parts are readily available and made
by every manufacturer and his dog.

I agree, one must take care in this respect.
