1
The min/max specifications are guaranteed over this range. The min/max values are typical over 3.0 V to 3.6 V.
2
Ambient temperature range T
MIN
to T
MAX
: −40°C to +85°C. The die temperature, T
J
, must always be kept below 110°C.
3
Guaranteed by characterization.
4
Full drive into 37.5 Ω load.
5
DACs can output 35 mA typically at 3.3 V (R
SET
= 150 Ω and R
L
= 37.5 Ω); optimum performance obtained at 18 mA DAC current (R
SET
= 300 Ω and R
L
= 75 Ω).
6
Minimum drive current (used with buffered/scaled output load).
7
Power measurements are taken with clock frequency = 27 MHz. Max T
J
= 110°C.
8
I
DAC
is the total current (min corresponds to 5 mA output per DAC, max corresponds to 38 mA output per DAC) to drive all four DACs. Turning off individual DACs
reduces I
DAC
correspondingly.
9
I
CCT
(circuit current) is the continuous current required to drive the device.
10
Total DAC current in sleep mode.
11
Total continuous current during sleep mode.
