Negative Error Sources voltages on the RS+ or RS- are beyond the sensing voltage range of this amplifier. There are 3 dominant error sources: gain error, input offset voltage error and Kelvin voltage error (see Figure79). The gain 0.5 error is dominated by the internal resistance matching 0.4 tolerances. The remaining errors appear as sense voltage errors 0.3 at the input to the amplifier. They are VOS of the amplifier and %) 0.2 Kelvin voltage errors. If the transient protection resistor is added, CY ( 0.1 an additional VOS error can result from the IxR voltage due to RA 0 input bias current.

GAIN ACCURACY vs VRS+ = 0V TO 2V The source of Kelvin voltage errors is illustrated in Figure79. The resistance of 1/2 Oz copper is ~1mΩ per square with a TC of Typical Application Circuit ~3900ppm/°C (0.39%/°C). When you compare this unwanted parasitic resistance with the total 1mΩ to 10mΩ resistance of Figure 80 shows the basic application circuit and optional the sense resistor, it is easy to see why the sense connection protection components for switched-load applications. For must be chosen very carefully. For example, consider a applications where the load and the power source is permanently maximum current of 20A through a 0.005Ωsense resistor, connected, only an external sense resistor is needed. For generating a VSENSE = 0.1 and a full scale output voltage of 10V applications where fast transients are caused by hot plugging the (G=100). Two side contacts of only 0.25 square per contact puts source or load, external protection components may be needed. the VSENSE input about 0.5x 1mΩ away from the resistor end The external current limiting resistor (RP) in Figure 80 may be capacitor. If only 10A the 20A total current flows through the required to limit the peak current through the internal ESD kelvin path to the resistor, you get an error voltage of 10mV diodes to <20mA. This condition can occur in applications that (10Ax0.5sq x 0.001Ω/sq. = 10mV) added to the 100mV sense experience high levels of in-rush current causing high peak voltage for a sense voltage error of 10% (0.110V-0.1)/0.1V)x100. voltages that can damage the internal ESD diodes.
