NOTES
1_{All supplies can be varied ± 5% and operation is guaranteed.}
2_{Guaranteed but not tested.}
3_{Operation is guaranteed over this reference range, but linearity is neither tested nor guaranteed.}
4_{VOUT swing between +10 V and –10 V.}
5_{All input control signals are specified with tr = tf =5 ns (10% to 90% of +5 V) and timed from a voltage level of 1.6 V.}
6_{Typical values indicate performance measured at +25°C.}
Specifications subject to change without notice.
