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.
