INA145 - Programmable Gain DIFFERENCE AMPLIFIER
The INA145 is a precision, unity-gain difference amplifier consisting of a precision op amp and onchip 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.
