7.3.2.1 The Shunt Resistor
Selection of the shunt resistor RSHUNT value is limited (in part) by the voltage drop that is developed by the maximum load-sharing current of the module. This voltage drop should be much less than the maximum voltage adjustment range ΔVADJ(max) of the module by at least a factor of 10, as shown in Equation 3.
Other limitations for RSHUNT include the maximum allowable power dissipation and available component ratings. On the other hand, the value of RSHUNT should be high enough to avoid signal degradation from noise or requiring excessive amplification by the CSA.
