LT1101

Precision, Micropower,

Single Supply Instrumentation

Amplifier (Fixed Gain = 10 or 100)

DESCRIPTIO

The LT

®

1101 establishes the following milestones:

(1) It is the first micropower instrumentation amplifier,

(2) It is the first single supply instrumentation amplifier,

(3) It is the first instrumentation amplifier to feature fixed

gains of 10 and/or 100 in low cost, space-saving 8-lead

packages.

The LT1101 is completely self-contained: no external gain

setting resistor is required. The LT1101 combines its

micropower operation (75µA supply current) with a

gain error of 0.008%, gain linearity of 3ppm, gain drift of

1ppm/°C. The output is guaranteed to drive a 2k load to

±10V

with excellent gain accuracy.

Other precision specifications are also outstanding:

50µV input offset voltage, 130pA input offset current, and

low drift (0.4µV/°C and 0.7pA/°C). In addition, unlike other

instrumentation amplifiers, there is no output offset

voltage contribution to total error.

A full set of specifications are provided with

±15V

dual

supplies and for single 5V supply operation. The LT1101

can be operated from a single lithium cell or two Ni-Cad

batteries. Battery voltage can drop as low as 1.8V, yet the

LT1101 still maintains its gain accuracy. In single supply

applications, both input and output voltages swing

to within a few millivolts of ground. The output sinks

current while swinging to ground—no external, power

consuming pull down resistors are needed.
