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 LT1720/LT1721 comparators include 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
TRIP+
and V
TRIP–
, while the hysteresis voltage is the difference of these two.
Note 4:
The common mode rejection ratio is measured with V
CC
= 5V
and is defined as the change in offset voltage measured from V
CM
=
–0.1V to V
CM
= 3.8V, divided by 3.9V.
Note 5:
The power supply rejection ratio is measured with V
CM
= 1V
and is defined as the change in offset voltage measured from V
CC
=
2.7V to V
CC
= 6V, divided by 3.3V.
Note 6:
Because of internal hysteresis, there is no small-signal region
in which to measure gain. Proper operation of internal circuity is
ensured by measuring V
OH
and V
OL
with only 10mV of overdrive.
Note 7:
Propagation delay measurements made with 100mV steps.
Overdrive is measured relative to V
TRIP
±
.
Note 8:
t
PD
cannot be measured in automatic handling equipment with
low values of overdrive. The LT1720/LT1721 are 100% tested with a
100mV step and 20mV overdrive. Correlation tests have shown that
t
PD
limits can be guaranteed with this test, if additional DC tests are
performed to guarantee that all internal bias conditions are correct.
Note 9:
Differential propagation delay is defined as the larger of the
two:
t
PDLH
= t
PDLH(MAX)
– t
PDLH(MIN)
t
PDHL
= t
PDHL(MAX)
– t
PDHL(MIN)
where (MAX) and (MIN) denote the maximum and minimum values of
a given measurement across the different comparator channels.
Note 10:
Propagation Delay Skew is defined as:
t
SKEW
= |t
PDLH
– t
PDHL
