1077 is a micropower precision operational
amplifier optimized for single supply operation at 5V. In
addition,
鹵15V
specifications are provided.
Micropower performance of competing devices is
achieved at the expense of seriously degrading precision,
noise, speed, and output drive specifications. The LT1077
reduces supply current without sacrificing other
parameters. The offset voltage achieved is the lowest
of any micropower op amp. 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.
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.
The LT1077 is completely plug-in compatible (including
nulling) with all industry standard precision op amps.
Thus, it can replace these precision op amps in many
applications without sacrificing performance, yet with
significant power savings.
The LT1077 can be operated from one lithium cell or two
Ni-Cad batteries. The input range goes below ground. The
all-NPN output stage swings to ground while sinking
current鈥攏o pull-down resistors are needed.
For dual and quad op amps with similar specifications
please see the LT1078/LT1079 datasheet.
