= 0V, T
A
= -40°C to +85°C, unless otherwise noted. Typical values are at T
A

Note 1: All specifications are 100% tested at T
A
= +25°C. Specification limits over temperature (T
A
= T
MIN
to T
MAX
) are guaranteed
by design, not production tested.
Note 2: V
OS
is defined as the center of the hysteresis band at the input.
Note 3: 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
) (Figure 2).
Note 4: Specified with an input overdrive (V
OVERDRIVE
) of 100mV, and load capacitance of C
L
= 15pF. V
OVERDRIVE
is defined
above and beyond the offset voltage and hysteresis of the comparator input. For the MAX917/MAX918, reference voltage
error should also be added.
