Great news(?)! Today I got a xerox with the data for the MAT-02
dual transistor made by PMI. Good log conformant dual transistors,
well suited for exp converters. The great news is that also a 
MAT-04 is available, with 4 matched transistors on a chip, and
it's even available. This looks like a perfect device for a 
substrate temperature controlled dual transistor! Cost here is
Dfl 35,-, which is ca US$20,- Same price as a LM394 or MAT-02!

S&H's a module and s&h's looking good
