Hi Sar and Joerg,
just a quick question:

Did it? I thought it was a bit slower in the beginning, but the
oscillation subsided just as fast as with the other opamp. Do you
guys have any top-of-the-head suggestions for replacements? Something
with < -96dB channel crosstalk and > 96dB SNR would be nice.
Regards,
Andreas
PS.
ACK means ACKnowledged. But perhaps we should use ARGH! more in our
conversations? ;o) Just kidding.

PPS.
A short progress report on TinyEEG:
I worked a bit on the power supply this weekend and have successfully
managed to reduce the HF noise to levels undetectable by oscilloscope.
Just to be sure, I will add a second filter stage identical to the
first, that in theory should reduce the HF-noise to 10-20uV.
Currently, there's only visible noise (2mVp-p) in the 0-10kHz range
left, but I hope a linear regulator can handle that.
Yes I know my project is moving forward at a crawl right now, a lot
going on... Joerg, how are you doing?
DS.
