LT1101 • TA01
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.
