ELECTRICAL CHARACTERISTICS (continued)

Note 1:

Note 2:

Inferred from PSRR test.

Note 3:

Inferred from CMRR test. Note also that either or both inputs can be driven to the absolute maximum limit (0.3V beyond either

supply rail) without damage or false output inversion.

Note 4:

Note 5:

The input-referred trip points are the extremities of the differential input voltage required to make the comparator output

change state. The difference between the upper and lower trip points is equal to the width of the input-referred hysteresis

zone. See Figure 1.

Note 6:

Note 7:

Note 8:

is in shutdown.

Note 9:

Specified between any two channels in the MAX9142/MAX9144.

Note 11: Applies to the MAX9141 only for both SHDN and LE.

Figure 2.

Note 13: Applicable to the MAX9141 only. Comparator is active with the SHDN driven high and is shutdown with SHDN driven low.

Shutdown enable time is the delay when the SHDN is driven high to the time the output is valid. Shutdown disable time is the

delay when the SHDN is driven low to the time the comparator shuts down.
