QI would like to supply ±7.5V in order to achieve ±4V on the output. This is in
relation to the data on page 2 of the datasheet which states that with a supply
of ±13V you can achieve ±10V output.
AThe AD698 was characterised with +/-13V dual supply and 17.5V single supply for
+/-10V output or 10V for single supply.
The peak values of VA, VB should be 2.5V less than the supply voltages.
While the part may work and most likely will work at lower supplies than those
specified, ADI does not guarantee the specs at lower voltages simply
because the part was not characterised for those voltages when initially
