Note 1: Absolute Maximum Ratings are those values beyond which the life of
a device may be impaired.
Note 2: The LTC1757A-1 and LTC1757A-2 are guaranteed to meet performance
specifications from 0 C to 70 C. Specifications over the – 30 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.
Note 5: This is the time from TXEN rising edge 50% switch point to
