[sdiy] Cheapest Matched Pair

[oleavitt at ix.netcom.com]

There is the CA3046 array - about US$1.00, or less, a piece.
The differential pair in this is matched to within 5 milli volts, which is
looser than the 50 micro volt match for the LM394, but good enough for many
applications.

I beleive there have been others mentioned on the List some weeks back...

Best Holiday wishes, Oren
