Power consumption and audio is impressive.

Hi i have a question I see from the DS that the OPA1611 has better THD+noise at around 6V Is there any opamp with similar excellent performance but at a lower voltage ? i do not need more that 2Vrms out It is the level than can drive almost any power amp to max power

Think she measured it with the retro-encabulator?

Awesome chips :-D Going to be rolling one of these (OPA1612) into the buffer section of my ASUS Xonar Essence STX, with 2x LT1364's in the I/V stage. From a circuit design point of view this should net some of the best sounding audio from a non-fully discrete design. Sound perfection, I can't wait.

I`m use OPA1612 in my Pioneer DV-300 and DV-410V DVD Players instead of RC4580 Op-Amps and difference in sound is more then good. Sound is clearer, more dynamic and something different with more pleasant on ears. I have good experience with OPA2134 and this chip was my first choice but after I decide to try somethin different and choose OPA1612, i dont want to go back.

How's the crossover distortion before closing the loop?
And what's the old opa211 high frequency thd looks over frequency domain,
bcs I saw on opa1612 datasheet, it looks pretty hard to achieve such improved result.

Need a new cheap and better solution over 1612.
