Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: Specifications are assured over the –40 C to 85 C temperature
range by design characterization and correlation with statistical process
controls.
Note 3: Slew rate is measured open loop. The rise time at V
measured between 1V and 2V.

The maximum load capacitance is 100pF. The output is
capable of rail-to-rail swings at low load currents. Selected
when BSEL is low.
