Hi Tony,

You're of course right. I forgot to say this. When you add a low impedance
HF feedback path most opamps will not oscillate.
The capacitor should be close to the opamp and have low inductance and low
esr. Ceramic disc is best. Few 100pF - 1nF

>The 5534 is OK for unity gain apps, IF you take precautions. You can

>a 5532 or OP275.


Bye,
Heiko
