Note 1:
Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2:
This parameter is guaranteed to meet specified performance
through design and characterization. It has not been tested.
Note 3:
The LT1671CS8 and LT1671CMS8 are guaranteed to meet
specified performance from 0
°
C to 70
°
C and are designed, characterized
and expected to meet these extended temperature limits, but are not tested
at –40
°
C and 85
°
C. The LT1671IS8 is guaranteed to meet the extended
temperature limits.
Note 4:
Input offset voltage (V
OS
) is defined as the average of the two
voltages measured by forcing first one output, then the other to 1.4V.
Note 5:
Input bias current (I
B
) is defined as the average of the two input
currents.
Note 6:
Input voltage range is guaranteed in part by CMRR testing and in
part by design and characterization.
Note 7:
t
PD
and
t
PD
cannot be measured in automatic handling
equipment with low values of overdrive. The LT1671 is 100% tested with a
100mV step and 20mV overdrive. Correlation tests have shown that t
PD
and
t
PD
limits can be guaranteed with this test, if additional DC tests are
performed to guarantee that all internal bias conditions are correct.
Propagation delay (t
PD
) is measured with the overdrive added to the actual
V
OS
. Differential propagation delay is defined as:
t
PD
= t
PDLH
– t
PDHL
Note 8:
Latch propagation delay (t
LPD
) is the delay time for the output to
respond when the LATCH pin is deasserted. Latch setup time (t
SU
) is the
interval in which the input signal must remain stable prior to asserting the
latch signal. Latch hold time (t
H
) is the interval after the latch is asserted in
which the input signal must remain stable.
