Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Note 1:
The MAX998EUT specifications are 100% tested at T
A
= +25°C. Limits over the extended temperature range are guaran-
teed by design, not production tested.
Note 2:
Inferred from CMRR test. Either input can be driven to the absolute maximum limit without false output inversion, as long as
the other input is within the common-mode voltage range.
Note 3:
V
OS
is defined as the mean of trip points. The trip points are the extremities of the differential input voltage required to make
the comparator output change state (Figure 1).
Note 4:
The difference between the upper and lower trip points is equal to the width of the input-referred hysteresis zone (Figure 1).
Note 5:
Propagation Delay is guaranteed by design. For low overdrive conditions, V
TRIP
(Figure 1) is added to the overdrive.
Note 6:
Propagation-Delay Skew is the difference between the positive-going and the negative-going propagation delay.
