DESCRIPTIO
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:
60µV offset voltage, 0.1nA offset current, in excess of
10mA output current at 330µA 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.
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 200µV 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.
