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