I have a question to the AD698. To reduce the power dissipation we like to supply this device with ±12V. The output voltage is ±5V with a exc. voltage of 2.2V rms. Is for this ±12V good enough?
I'm afraid we don't have a lot of information on this part. I know that it will work with +/-9V supplies. I have a note from the original designer (who is no longer in ADI) which says that it can be made to work at +/-8V by either moving the ground to make it +10V, -6V or by offsetting the output to operate in unipolar mode. I have set it up on the bench with +/-6.5V supplies and it seems to work but this is not a guarantee. I think you should ask the customer if he can increase his supplies to at least +/-9V. You should also make sure he is aware that the datasheet specs are not guaranteed when using supply voltages less than those recommended in the datasheet. We do not have any characterisation data on supplies below those in the datasheet.
