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.
