1. VOS is defined as the center of the hysteresis band at the input.

2. The hysteresis-related trip points are defined as the edges of the hysteresis band, measured with respect to the

center of the band (i.e., VOS) (see Figure 26 on page 11).

3. Guaranteed by design.

4. Specified with an input overdrive voltage (VOVERDRIVE) = 100mV, and load capacitance (CLOAD) = 15pF. VOVER-

DRIVE

is defined above and beyond the offset voltage and hysteresis of the comparator input. A reference volt-

age error should also be added.
