INA125UA (TEXAS INSTRUMENTS)

The INA125UA 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 10000. The INA125 is laser-trimmed for low offset voltage 250µV, low offset drift 2µV/°C and high common-mode rejection (100dB at G=100). It operates on dual ±1.35 to ±18V supplies. The voltage reference is externally adjustable with pin selectable voltage, allowing use with a variety of transducers. The reference voltage is accurate to ±0.5% maximum with ±35ppm/°C maximum drift. Sleep mode allows shutdown and duty cycle operation to save power.
