Hi

 

I'd like to know how to calculate the input current of LTC2620 reference input. The resistance under Normal Mode condition is 16kohm typ. When the reference voltage is +2.5V, may I calculate the current as 2.5V/16kohm = 0.15mA? Otherwise 0.15mA*8=1.2mA, because there are 8 DACs in LTC2620.   

 

Regards,

Hiroyuki
