DESCRIPTIO
The LT
8-pin configuration; the LT1179 is a micropower quad op
amp offered in the standard 14-pin packages. 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.
