Product Summary
The INA145UA is a precision, unity-gain difference amplifier consisting of a precision op amp and on-chip precision resistor network. Two external resistors set the gain from 1V/V to 1000V/V. The input common-mode voltage range extends beyond the positive and negative rails. The applications of the device include current shunt measurements, sensor amplifier, differential line receiver and battery powered systems. The INA145UA is available in the SO-8 surface-mount package specified for the extended industrial tempera-ture range, –40℃ to +85℃.
