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.
