DACs can output 35 mA typically at 2.8 V (R
SET
= 150 Ω and R
L
= 37.5 Ω). Full drive into 37.5 Ω load.
4
Power measurements are taken with clock frequency = 27 MHz. Max T
J
= 110°C.
5
I
DAC
is the total current (min corresponds to 5 mA output per DAC, max corresponds to 37 mA output per DAC) to drive all three DACs. Turning off individual DACs
reduces I
DAC
correspondingly.
6
I
CCT
(circuit current) is the continuous current required to drive the device.
7
Total DAC current in sleep mode.
8
Total continuous current during sleep mode.
