Single Supply Instrumentation

DESCRIPTIO

The LT

(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.
