Ok here it goes again
First of all thanks for the reply.
Well I now use a +35 -35 supply.
Also checked the printed circuit. There are no short there.
There are no capisitor to the feedback, but am using the circuit that National has at the first page of the datasheet.
Have even try to short the output with the input to set it to 1 gain.
Still get the same +35 at the output, like there is no negative suppy. but THERE IS.
Am having a hart time here, it is the first time I use complementary supply ( i say that again) and well, am a bit confused.
Thanks again for any help
