INA125

The INA125 is a low power, high accuracy instrumentation amplifier with a precision voltage reference. It provides  omplete 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 (250V), low offset drift (2V/), 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 of the INA125 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 to +85 industrial temperature range.
