[sdiy] Matched dual NPN

[Andrew Ison]

And just as i buy the LM394's too,i notice the self same supplier stocks 
these SSM2210's at a slightly cheaper price!

Farnell in the uk.

Only now it seems i have to manipulate tiny SMD Temperature sensing 
resistors,but of course no 3300ppm.

And yet whilst i noted the standard logic of adding series resistor to do 
something with a 3900 ppm Ik version to make it useful i could not help but 
wonder if i were to use two parallel 3000ppm at 3k with another 3k in 
parallel rated at 3900ppm i would have a 1k 3300ppm.

Would it work?

I look for details of tempco used this way but had to abandon the search.
