amps" and filter for 4 units per package in through hole format, you get like 21
hits, none of which include any of the opamps I'm already aware
of.</FONT></SPAN></DIV>

class=quote>Hey Team,<BR><BR>I'm looking for opamps with the following
properties:<BR><BR>1) Through-hole<BR>2) Quad opamp<BR>3) 14-DIP
package<BR>4) High power range (+/-18V, say)<BR>5) Low input bias current
(10 pA or less typical)<BR>6) Pin-compatible with TL074, etc.<BR>7) Not
LF444 (cuz they all seem to be defective)<BR><BR>So, basically, I'm looking
for a suitable alternative for LF444.<BR><BR>So, here are my
questions:<BR><BR>A) Do you know of such a thing<BR>B) How does one go about
finding such a thing, generally?<BR><BR>Thanks in advance!<BR>Dave (Floating
VCA)
