DESCRIPTION
The LT
®
2078 is a micropower dual op amp in 8-pin small
outline, standard surface mount package, and LT2079 is
a micropower quad op amp offered in the standard 14-pin
surface mount package. 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 LT2078/LT2079 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.
Both the LT2078/LT2079 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 resis-
tors are needed. For applications requiring DIP packages
refer to the LT1078/LT1079.
