The LT1413 is optimized for single 5V applications, although ± 15V specifications are also provided for pleteness. In the design of the LT1413, particular emphasis has been placed on low cost plastic and SO-8 package performance: 60µV offset voltage, 0.1n A offset current, in excess of 10m A output current at 330µA supply current and 140d B channel separation are some of the specifications achieved. Other dual, single supply amplifiers are available to plement the LT1413 family: the micropower LT1078’s supply current is 10 times lower with a 4.5 fold speed performance degradation pared to the LT1413. Conversely, the LT1211, LT1213 and LT1215 duals have 4 to 14 times higher supply current, but also 13 to 50 times higher speed. Protected by U.S. Patent 4,775,884.
