OPA643 - looks like a good one

[carlosfm]

Has someone tried the OPA843 op-amp?
Looks like a good candidate for a battery-powered headamp or even phono preamp.
Max. supply voltage +/- 6.5 volts!
Very low noise.
Just take a look at the datasheet here:

i dunno due to this spec:
"Acl, min stable gain (V/V) = 3"

kinda kills sallen-key type filters and many of the circuts which operate at unity gain.

oh, yeah, i guess for a preamp it would be ok, my bad.
