ADS1263: Shut resistor recommendation

Part Number: ADS1263

Hello,

Can you please recommend an optimize shunt resistor to sense current?

Is there any technical document describng how to select shurt resistor values?

This is simple structure of the system:

PMIC(ex. 1.1V supply) ------(ADS1263 input P) Shunt resistor 10mohm (ADS1263 input N)-------device for current measuring

 Here is ADS1263 design parameters:

1. AVDD : 5V

2. DVDD : 3.3V

3 Ref Voltage : internal 2.5V

4. PMIC supply range : 0.5V~3.3V

5. current range : 0mA ~ 500mA

Thanks!
