Описание

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. The voltage reference is externally adjustable with pin-selectable voltages, allowing use with a variety of transducers. Sleep mode allows shutdown and duty cycle operation to save power.
