The LT1413 is a low cost, upgraded version of Linear
Technology's industry standard LT1013 dual, single sup-
ply op amp. The LT1413 is optimized for single 5V appli-
cations, although
15V specifications are also provided
for completeness.
In the design of the LT1413, particular emphasis has been
placed on low cost plastic and SO-8 package performance:
60
V offset voltage, 0.1nA offset current, in excess of
10mA output current at 330
A supply current and 140dB
channel separation are some of the specifications achieved.
Other dual, single supply amplifiers are available to
complement the LT1413 family: the micropower LT1078's
supply current is 10 times lower with a 4.5 fold speed
performance degradation compared to the LT1413. Con-
versely, the LT1211, LT1213 and LT1215 duals have 4 to
14 times higher supply current, but also 13 to 50 times
higher speed.

The
q
denotes specifications which apply over the full operating
temperature range.
Note 1: Typical parameters are defined as the 60% yield of parameter
distributions of individual amplifiers; i.e., out of 100 LT1413s typically 120
op amps will be better than the indicated specification.
Note 2: This parameter is tested on a sample basis only. All noise
parameters are tested with V
S
=
2.5V, V
O
= 0V.
Note 3: This parameter is guaranteed by design and is not tested.
V
S
=
15V, T
A
= 25
C, unless otherwise noted.
Note 4: Gain-Bandwidth Product is not tested. It is inferred from the slew
rate measurement.
Note 5: This parameter is not 100% tested.
Note 6: At the minimum supply voltage, the offset voltage changes less
than 200
V compared to its value at 5V, 0V.
Note 7: The LT1413 is not tested and is not quality-assurance sampled at
40
C and at 85
C. These specifications are guaranteed by design,
correlation and/or inference from 0
C, 25
C and/or 70
C tests.
