/* ---------- "1458/4558 pin compatable op-amps?" ---------- */

	I'm looking for pin-compatable replacements for 1458/4558 op-amps.
It's for an audio application, so I'm looking for the best frequency response
(secondary) and the lowest noise (primary).  I intend to buy a few different
types and play around with different combinations, so I'm trying to find a
variety.  Are there any ones that have a FET *output* stage, or don't such
things exist?  I'd also like to get addresses for places from which I can order
these.  What I have so far is:
	TL082 (available from Radio Schlock for 1.98, any mail order?)
	Analog Devices AD712 
Much thanks.

Gawd, you're asking for a complicated answer.  Unlike single- and
quad-op-amp packages, duals are pretty standard; virtually all of them
follow the 1458 pinouts.

Here are a few:

Manufacturer	Part	Inputs	Notes
------------------------------------------------------------------------
TI		TL062	JFET	Low power

Digi-Key (1-800-344-4539) stock a lot of these; a quick glance through
their current catalog shows (They've probably got others):

Price Part                Price Part                Price Part
0.52 MC1458N (DIP)	  0.51 LM358N (DIP)	    0.77 NE532
0.56 MC1458D (SO-8 can)	  0.54 LM358M (SO-8 can)    1.24 NE5512
1.70 CA3240		  1.74 LF412		    1.85 NE5532
2.20 CA3260		  0.48 MC4558CD (SO-8 can)  3.95 NE5535
1.05 LF353		  0.48 MC4558CN (DIP)	    1.35 LM833

Jameco in California is also a good source of this sort of stuff;
unfortunately, I don't have their catalogue here in the office today.
I know that they stock TL082s; I've ordered them from there before.

For your application, the NE5532 sounds like a good bet.  Better look
at tha data sheet to make sure that it's fully compatible,
`pin-compatible' parts ofthen have a few `gotcha's somewhere.
