Something for DAC and "balanced" guys

Check out this IC. What do you think?

ULTRA LOW DISTORTION: 0.000022%

LOW NOISE: 1.3nV/√Hz

Neat even the settling time is ok.
Does anyone know why they specify slew rate and rise and fall time of a step, seems to be the same to me?

-133dB distortion

Slew rate is not exactly the same a rise time in an amp which has feedback.

Slew rate is the absolute maximum rising speed when the amp is overdriven.

It's interesting that TI/BB puts OPA 134, 627 and 227 as "related" devices. I wonder what that means...

The chip certainly looks good, and it might be an interesting chip to try as single to balanced converter, as they say it can be used.

They do look good indeed! I got some recently, haven't tried them yet...
I'll try to attach my quick and dirty pcb layout from expresspcb.

PSz.

... I tried to attach, but improper file extension, and Bitmap export lost the traces. Oh well it wasn't much to see anyhow

Thanks for the heads up; this may be useful in my next project! At the least, it will be once of several approaches compared.
