Description

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.

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.

The INA145 is available in the SO-8 surface-mount package specified for the extended industrial temperature range, 40 to +85.
