I have a question about S1 and S0 setting of HMC980LP4E for HMC637ALP5E(Idd=400mA).

According to the Table 1 in the datasheet of HMC980LP4E, S1 should be set to GND and S0 should be set to VDIG for 0.3 to 0.6A. But, according to the Table 3 in the datasheet, S1 and S0 should be set to GND for HMC637LP5E. This setting is for 0.05 to 0.3A in the Table 1. Which is correct? Or, can we use the setting of S1=S0=GND for 400mA?


Best regards,
