What is the lowest shunt value I can use with these ADE7912/ADE7913 or
ADE7932/ADE7933?

 

These devices have been designed to be used with shunt values of at least 180
µΩ. Because the maximum voltage at the current channel ADC is 31.25mVpeak, this
means the full scale current for a 180 µΩ shunt is
(31.25* 10^-3) / ( sqaurt 2 * 180 * 10^-6)
= 122.76 Arms
