Dual RTR op amp favorites

I like the TLE2142 (dual), also available in single and quad, for many of its abilities (5V, rail to rail, semi-beefy output current in the

10's of mA's if not quite 50mA) that you are looking for.

That said, it's not the most obvious choice for a demanding audio (low noise? low distortion?) application.

CMOS Op-amps with supplies limited to no more than 6 or 7V are becoming increasingly popular, and might fit your needs. You don't mention a max power supply, only a min...

Well.... few op-amps aren't capable of audio frequency operation ! I guess you meant 'optimised for audio' ?

If you want low noise - low THD etc for audio you simply won't find any

*best* device that meets all your criteria.

Low input noise requires highish front end current for example - just for starters.

Dual op-amps are no big problem though. I'd say they were the most popular packaging.

Perhaps you could list your requirements in order of proprity and what performance levels you're seeking ?

I have checked mfr's spec sheets but need a bit of direction. Could I ask for a few recommendations for readers' favorite op amps with the characterisitcs listed below.



Some amps that fit are relatively expensive and probably more than I need. What is the simplest and most cost-effective option for audio frequency.



Single supply down to 4V Low power Dual amps in DIP pkg. Rail-to-rail output



50ma output current

Other parameters are not critical.



Thank you, Louis
