MAT 02 etc

[Grant Richter]

Just a note:

Dual NPN - MAT-02, LM394, SSM2210

Dual PNP - MAT-03, SSM2220

Also Linear Systems

http://www.linearsystems.com

make lots of nice log conformance matched pairs
like the LS358 dual PNP. About $5 in small quant.
Rbe is around an ohm so the SSM & MAT units
with 0.3 ohm Rbe require less compensation.
But $5 is a lot cheaper than the $13.98 for a MAT-03.
