GENERAL PURPOSE INSTRUMENTATION
DESCRIPTION
The INA125 is a low power, high accuracy instrumen-
tation amplifier with a precision voltage reference. It
provides complete bridge excitation and precision dif-
ferential-input amplification on a single integrated
circuit.
A single external resistor sets any gain from 4 to
10,000. The INA125 is laser-trimmed for low offset
voltage (250
μ
V), low offset drift (2
μ
V/
°
C), and high
common-mode rejection (100dB at G = 100). It oper-
ates on single (+2.7V to +36V) or dual (
±
1.35V to
±
18V) supplies.
The voltage reference is externally adjustable with pin-
selectable voltages of 2.5V, 5V, or 10V, allowing use
with a variety of transducers. The reference voltage is
accurate to
±
0.5% (max) with
±
35ppm/
°
C drift (max).
Sleep mode allows shutdown and duty cycle operation
to save power.
The INA125 is available in 16-pin plastic DIP and
SO-16 surface-mount packages and is specified for
the –40
°
C to +85
°
C industrial temperature range.
