The LT1178S8 is a micropower dual op amp in the surface mount 8-pin package. It is optimized for single supply operation at 5V. Specifications are also provided at 15V supplies. The extremely low supply current is combined with true precision specifications: offset voltage is 60V, 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 of megohm level source resistors without introducing serious errors. Voltage noise at 0.9VP-P is remarkably low considering the low supply current. The LT1178S8 can be operated from a single supply as low as one lithium cell or two Ni-Cad 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 applications where three times higher supply current is acceptable, the micropower LT1077 single, LT1078 dual and LT1079 quad are recommended. The LT1077/ LT1078/LT1079 have significantly higher bandwidth, slew rate; lower voltage noise and better output drive capability.
