6.3.1 Gain Error and Drift

Gain error in the INA105 is limited by the mismatch of the integrated precision resistors. Gain drift is limited by the slight mismatch of the temperature coefficient of integrated resistors. The integrated resistors are precision-matched with low temperature coefficient resistors to improve overall gain drift compared to the discrete implementation of differences amplifiers build when using external resistors.
