The LT2178 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 combined with true precision specifications: offset voltage is 30μV and offset current is 50pA. Both offset parameters have low drift with temperature. The 1.5pAP-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 NiCd 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.
For surface mount applications where three times higher supply current is acceptable, the micropower LT1077 single, LT2078 dual and LT2079 quad are recommended. The LT1077/LT2078/LT2079 have significantly higher bandwidth, slew rate, lower voltage noise and better output drive capability. For applications requiring DIP packages refer to the LT1178/LT1179.
