The INA125 is a low power, high accuracy instrumentation
amplifier with a precision voltage reference. It
provides complete bridge excitation and precision differential-
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 (250mV), low offset drift (2mV/°C), and high
common-mode rejection (100dB at G = 100). It operates
on single (+2.7V to +36V) or dual (±1.35V to
±18V) supplies.
The voltage reference is externally adjustable with pinselectable
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.
