national app notes

[Martin Czech]

Today I loaded some national app notes.

http://www.national.com/
 
Look for app notes.

Use the search engine.

I found this to be usefull:

LB-39.pdf  some comments about comparators, ocillation supression, trimimg offset
AN-74.pdf  page 14, usefull temperature sensor using npn, 
           applications for comparators (not sensational)
AN-286.pdf just for fun : page 4, another obscure VCO with 3045 array and chip heater
