DESCRIPTIO

The LT

amplifier optimized for single supply operation at 5V. In

addition, ±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—no pull-down resistors are needed.

For dual and quad op amps with similar specifications

please see the LT1078/LT1079 datasheet.
