Are these guys serious ?

A brand new Burr Brown power op-amp that puts out 2A on a 5V power supply and idles at 9 mA ?

I have no idea how this part sounds but this is power amp territory .

I NEED to play with htis guy !

With a supply voltage range of 2.7 to 5.5V, a slew rate of 1.2V/uS, and a PSRR of 50db at 10kHz, it does not look like a good chip for audio use.

psrr means not a whole lot if supply regulation is used.
The 2.7 to 5 volts is more than enough when you consider it swing the signal up to supply voltages.Who needs more than 2 volts ?

And slew rate is more of a "looky my slew rate" than an indication of need . I would love for it to be around 10 or so butagain this is workable.

And the current potential , especially bridged or paralleled is scary !

Only thing to do isget my hands on a couple and check it out

yes it is , but the above is surprising due to portable possibilites.Bearing in mind the full 2 amps would be overkill but add the current limit feature set at say 400 ma , and the turnoff feature set set to trigger with a dac mute I just seen possibilities.

more than likely sounds like crap though .

2 Volts is pathetic, especially for medium to high impedance headphones.
