In Reply to: Re: Op Amps running Class A? posted by Ryan on March 23, 2001 at 04:19:53:
If I am using a dual Opamp (BB OPA2604) I connect a 5 kohm R between pin 4 (-V) between/across both pin 1 (output A) and pin 7 (output B)? Therefore 2 resistors required for each dual opamp?Thanks in advance.
Follow Ups:
I've added a 0.25 Watt 5Kohm 1% resisitor on the opa2604's of my preamp. That is one resistor per 2604 chip, from pin 4 to pin 7. I didn't mount any heat sink, but up to now about 3 hours, everything is good.
Amazingly sweet !!Thank you, all of you.
unless you get some heatsinking on that. It'll just burn out sooner on you, and still could just overheat on you soon. Get the heatsink and be safe. Op-amp's dont like to run very hot anyway.
They run really hot. Thank you Andy.
Your advice is reasonable. I'm now building some tiny heatsinks using metal fuse holders. I'll stick them to the chips using heat dissipating gel.
Thank you Andy !!!
