ELECTRICAL CHARACTERISTICS (continued)

= +2.7V to +5.5V, V

CM

= 0V, T

A

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

A

= +25°C.) (Note 1)

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.

Note 7:

For design purposes, the t

EN

can be as high as 60µs.
