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

µV offset voltage, 0.1nA offset current, in excess of

10mA output current at 330

µA 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.
