Texas Instruments INA145

esistors are laser-trimmed to achieve accurate gain and high common-mode rejection. Ex-cellent TCR tracking of these resistors assures contin-ued high

The INA145 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 com-mon- 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. Ex-cellent TCR tracking of these resistors assures contin-ued high precision over temperature.The INA145 is available in the SO-8 surface-mount package specified for the extended industrial tempera-ture range, -40°C to +85°C.
