The LT®1078 is a micropower dual op amp in 8-pin
packages including the small outline surface mount pack-
age. The LT1079 is a micropower quad op amp offered in
the standard 14-pin packages. Both devices are optimized
for single supply operation at 5V. ±15V specifications are
also provided.
Micropower performance of competing devices is achieved
at the expense of seriously degrading precision, noise,
speed and output drive specifications. The design effort of
the LT1078/LT1079 was concentrated on reducing sup-
ply current without sacrificing other parameters. The
offset voltage achieved is the lowest on any dual or quad
nonchopper stabilized op amp—micropower or other-
wise. Offset current, voltage and current noise, slew rate
and gain bandwidth product are all two to ten times better
than on previous micropower op amps.
The 1/f corner of the voltage noise spectrum is at 0.7Hz,
at least three times lower than on any monolithic op amp.
This results in low frequency (0.1Hz to 10Hz) noise
performance which can only be found on devices with an
order of magnitude higher supply current.
Both the LT1078 and LT1079 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.
