The LT®2178 is a micropower dual op amp in a surface mount standard 8-pin configuration, the LT2179 is a micropower quad op amp offered in a surface mount 14-pin package. Both devices are optimized for single supply operation at 5V. Specifications are also provided at ±15V supply. The extremely low supply current is bined with true precision specifications: offset voltage is 30μV and offset current is 50p A. Both offset parameters have low drift with temperature. The 1.5p AP-P current noise and picoampere offset current permit the use the megohm level source resistors without introducing serious errors. Voltage noise, at 0.9μVP-P, is remarkably low considering the low supply current. The LT2178/LT2179 can be operated from a single supply (as low as one lithium-cell or two Ni Cd batteries). The input range goes below ground. The all-NPN output stage swings to within a few millivolts of ground while sinking current. No power consuming pull down resistors are needed.
