ELECTRICAL CHARACTERISTICS The
l
denotes the specifi cations which apply over the full operating temperature range, otherwise specifi cations 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 specifi ed.

Note 1:
Stresses beyond those listed under Absolute Maximum Ratings VEE = – 5.5V to VEE = 0V divided by 5.5V, or the change in offset voltage may cause permanent damage to the device. Exposure to any Absolute from VCC = +VS = 2.7V to VCC = +VS = 6V (with VEE = 0V) divided by 3.3V. Maximum Rating condition for extended periods may affect device
Note 7:
The LT1719S6 power supply rejection ratio is measured with reliability and lifetime. VCM = 1V and is defi ned as the change in offset voltage measured from
Note 2:
If one input is within these common mode limits, the other input V+ = 2.7V to V+ = 6V, divided by 3.3V. can go outside the common mode limits and the output will be valid.
Note 8:
Because of internal hysteresis, there is no small-signal region in

The LT1719 comparator includes internal hysteresis. The trip which to measure gain. Proper operation of internal circuity is ensured by points are the input voltage needed to change the output state in each measuring VOH and VOL with only 10mV of overdrive. direction. The offset voltage is defi ned as the average of V + – TRIP and VTRIP ,
Note 9:
Propagation delay measurements made with 100mV steps. while the hysteresis voltage is the difference of these two. Overdrive is measured relative to V ± TRIP .

tPD cannot be measured in automatic handling equipment with VCC = 5V, VEE = –5V and is defi ned as the change in offset voltage measured low values of overdrive. The LT1719 is 100% tested with a 100mV step from VCM = –5.1V to VCM = 3.8V, divided by 8.9V. and 20mV overdrive. Correlation tests have shown that tPD limits can be
