The maximum gain error of the INA183 is 0.4% and is specified over the full operational temperature range. The low gain error allows for accurate measurements as the sense voltage increases, and is designed for applications that need to detect overcurrent conditions accurately. The offset voltage of the INA183 is specified to be ±170 μV for all gain options. The low offset voltage allows for increased accuracy when the sense voltage is small or allows for reduction in the size of the current sense resistor with less impact on the total measurement accuracy. Smaller value resistors reduce the power loss in the application which allows the use of lower wattage resistors that are generally lower cost.
