Gain error in the INA600 is dictated by the mismatch of the integrated precision resistors. Gain error is a tested parameter and maximum gain error is under or at ±0.05% for all gains. Gain drift of the INA600 is limited by the mismatch of the temperature coefficient of the integrated resistors. Maximum gain drift is under 5ppm/°C for all gains. These integrated resistors are already precision matched with low temperature coefficient resistors. Thus, the overall gain drift is much better in comparison to discrete implementation of difference amplifiers built using external resistors. Gain drift is not a tested parameter and the maximum gain drift is specified based on characterization results with sufficient guard banding. Maximum gain error of ±0.05% is expected for inputs from the reference pin that sets output common-mode voltage.
