Description

The LT ®2078 is a micropower dual op amp in 8-pin small outline, standard surface mount package, and LT2079 is a micropower quad op amp offered in the standard 14-pin surface mount package. 

Both devices are optimized for single supply operation at 5V. ±15V specifications are also provided. Micropower performance of competing devices is achieved at the expense of seriously degrading precision, noise, speed and output drive specifications. The design effort of the LT2078/LT2079 was concentrated on reducing supply current without sacrificing other parameters. 

The offset voltage achieved is the lowest on any dual or quad nonchopper stabilized op ampmicropower or otherwise. Offset current, voltage and current noise, slew rate and gain bandwidth product are all two to ten times better than on previous micropower op amps. Both the LT2078/LT2079 can be operated from a single supply (as low as one lithium cell or two NiCd batteries). 

The input range goes below ground. The all NPN output stage swings to within a few millivolts of ground whilesinking current no power consuming pull-down resistors are needed. For applications requiring DIP packages refer to the LT1078/LT1079.
