NOTES
1The max/min specifications are guaranteed over this range. The max/min values are typical over 4.75 V to 5.25 V.
2Temperature range T
MIN to TMAX: 0°C to +70°C.
3Characterized by design.
4Full drive into 75
Ω doubly terminated load.
5Minimum drive current (used with buffered/scaled output load).
6Full drive into 150
Ω load.
7Specification guaranteed by characterization.
8I
DAC is the total current (“min” corresponds to 5 mA output per DAC, “max” corresponds to 8.66 mA output per DAC ) to drive DACs A, B, C, D, E, F. Turning off
individual DACs reduces IDAC correspondingly, also DACs A, B, C can be configured to output a max current of 37 mA but DAC D, E, F must be turned off.
9All six DACs on (DAC A, B, C, D, E, F).
10I
CCT (Circuit Current) is the continuous current required to drive the device.
11Only large DACs (DACs A, B, C) on per low power mode.
12Total DAC current in Sleep Mode.
13Total continuous current during Sleep Mode.
Specifications subject to change without notice.
