heady 0 Report post Posted November 24, 2004 Hi all the DIY gurus, I would like to know which opamp has the most optimal audio quality/power consumption ratio in your opinion. I am building a battery powered 3-channel CMOY, ie 2 opamps, for a friend and want to know which opamp will sound good and use the battery longest. Thanks. BTW - seems this site was down today? Am I right? Share this post Link to post Share on other sites
Firefox 0 Report post Posted November 24, 2004 If you can design the circuit to accomodate the opamp, the LM6171/ 6172 sounds very good while having fairly low quiesent current. Unfortunately, you may need to up the voltage to get decent voltage swing at high volumes for high-impedance headphones (250ohms up). Share this post Link to post Share on other sites
tropicalrips 0 Report post Posted November 24, 2004 can look at some of the Maxim op-amps, i hav used MAX4167 before, rated 2.5 to 6v, good for single 9v amps. they hav a few op-amps that are design for portable players that can drive headphones but not possible for DIY work direct headphone driver Share this post Link to post Share on other sites
