Baising Op Amps for Class A
 
Can someone please outline the basics for biasing opamps to work in class A.

What are safe operating currents in relation to thermal limits?:p

can it work?

I think it only force one arm of the output-stage into class A.

Hi,

Useful info can be found at http://www.audioasylum.com/audio/twe...es/31186.html,

And if you like to toy with current sources instead of resistors, see http://www.audio.nl/tipseng.html

Hope this helps,

François
