[sdiy] wow! this is neat!

apparently you can make a lookup table to change the resistance depending on 
temperature. it is programmable and non-volatile to boot which means you can 
set it and forget it. this sounds interesting for use in temperature stable 
VCO's and such but are 2 degree increments sufficient for that?

also, the power supply range for the device is 3Vdc-5.5Vdc and the voltage 
through it's resistors cannot be above the supply... hmmm that sucks.


anybody seen/used this thing?

ps: also found some sources for reverse taper pots, CA3046s, MC3900s, and 
4558s. if ya need em let me know.
