Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2:
A heat sink may be required to keep the junction temperature
below absolute maximum when the output is shorted continuously.
Note 3:
T

according to the following formulas:
LT1187MJ8, LT1187CJ8:

Note 4:
When R
L
= 1k is specified, the load resistor is R
FB1
+ R
FB2
, but
when R
L
= 300
Ω
is specified, then an additional 430
Ω
is added to the
output such that (R
FB1
+ R
FB2
) in parallel with 430
Ω
is R
L
= 300
Ω
.
Note 5:
V
OS
measured at the output (Pin 6) is the contribution from both
input pair and is input referred.

Note 9:
Settling time measurement techniques are shown in “Take the
Guesswork Out of Settling Time Measurements,” EDN, September 19,

Note 10:
NTSC (3.58MHz).
Note 11:
AC parameters are 100% tested on the ceramic and plastic DIP
packaged parts (J8 and N8 suffix) and are sample tested on every lot of
the SO packaged parts (S8 suffix).
Note 12:
