Is it possible to operate the AD698 from a +/- 12 volt supply as it states the minimum DC dual supply should be +/- 13 V in the data sheet and if so are there any compromises in the performance of the device apart from a smaller output swing.
Besides the output voltage range, the rest of the data sheet is valid if +/- 12 V supplies are used. Also the Typical Performance Characteristics plots cover a range of supplies from +/-12 V to +/-18 V. Ensure that a headroom of 3V is maintained when designing the output signal.
