Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: Specifications over the – 40 C to 85 C operating temperature range
are assured by design, characterization and correlation with statistical
process controls.
Note 3: Slew rate is measured open loop. The slew time at V
measured between 1V and 2V.
Note 4: Maximum DAC zero-scale offset voltage that can be applied to PCTL.
