Power consumption of LTC2620 Vref


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.

  •    Yes, that is the way to calculate the current on the reference of the LTC2620.   If you are using 8 channels you it will be about 1.2mA
