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., V
OS
)
(see Figure 26 on page 11)
.
3. Guaranteed by design.
4. Specified with an input overdrive voltage (V
OVERDRIVE
) = 100mV, and load capacitance (C
LOAD
) = 15pF. V
OVER-
DRIVE
is defined above and beyond the offset voltage and hysteresis of the comparator input. A reference volt-
age error should also be added.
