ADVANCE INFORMATION
The INA790x features external adjustable gain with two external resistors as described in Adjustable Gain Set Using External Resistors. The tolerance of these external resistors contribute to the total gain error of the system. These resistors are recommended to be of same kind so that temperature drift of these resistor track closely. Equation 4 can be used for calculating total error contributed by two external gain resistors.
