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 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 curr...
