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 programmable gain amplifier's on-chip precision resistors are laser-trimmed to achieve accurate gain and high common-mode rejection. Excellent TCR tracking of these resistors assures continued high precision over-temperature.
