Both devices are 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 30µV, 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 megaohm level source resistors without introducing serious errors. Voltage noise, at 0.9µVp-p, is remarkably low considering the low supply current. Both the LT1178 and LT1179 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 applications where three times higher supply current is acceptable, the micropower LT1077 single, LT1078 dual and LT1079 quad are recommended. The LT1077/78/79 have significantly higher bandwidth, slew rate, lower voltage noise and better output drive capability.

Note 2: Typical parameters are defined as the 60% yield of parameter distributions of individual amplifiers; (i.e., out of 100 LT1179s, or 100 LT1178s, typically 240 op amps, or 120, will be better than the indicated specification). Note 3: This parameter is tested on a sample basis only. All noise parameters are tested with VS = ±2.5, VO = 0V. Note 4: This parameter is guaranteed by design and is not tested. Note 5: Power supply rejection ratio is measured at the minimum supply voltage. The op amps actually work at 1.7V supply but with a typical offset skew of –300µV. Note 6: This parameter is not 100% tested. Note 7: During testing at –40°C, the 5V power supply turn on-time is less than 0.5 seconds.
