Single Supply Operation:
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.

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.
