ELECTRICAL CHARACTERISTICS The q denotes specifications that apply over the full operating temperature

range, otherwise specifications are at TA = 25°C. VCM = 1V, VSHDN = 0.5V, VOVERDRIVE = 20mV, COUT = 10pF and for the LT1719S8

VCC = +VS = 5V and VEE = –5V, for the LT1719S6 V

+ = 5V, V– = 0V, unless otherwise specified.

Note 1: Absolute Maximum Ratings are those values beyond which the

life of a device may be impaired.

Note 2: If one input is within these common mode limits, the other

input can go outside the common mode limits and the output will be

valid.

Note 3: The LT1719 comparator includes internal hysteresis. The trip

points are the input voltage needed to change the output state in each

direction. The offset voltage is defined as the average of VTRIP+ and

VTRIP

–, while the hysteresis voltage is the difference of these two.

Note 4: The LT1719S8 common mode rejection ratio is measured with

VCC = 5V, VEE = – 5V and is defined as the change in offset voltage

measured from VCM = – 5.1V to VCM = 3.8V, divided by 8.9V.

Note 5: The LT1719S6 common mode rejection ratio is measured

with V+ = 5V and is defined as the change in offset voltage measured

from VCM = –0.1V to VCM = 3.8V, divided by 3.9V.

Note 6: The LT1719S8 power supply rejection ratio is measured with

VCM = 1V and is defined as the worst of: the change in offset voltage

from VEE = – 5.5V to VEE = 0V divided by 5.5V, or the change in offset

voltage from VCC = + VS = 2.7V to VCC = + VS = 6V (with VEE = 0V)

divided by 3.3V.

Note 7: The 1719S6 power supply rejection ratio is measured with

VCM = 1V and is defined as the change in offset voltage measured from

V+ = 2.7V to V+ = 6V, divided by 3.3V.
