NOTES
1
Oversampling disabled. Static DAC performance will be improved with increased oversampling ratios.
2
DNL measures the deviation of the actual DAC output voltage step from the ideal. For +ve DNL, the actual step value lies above the ideal step value; for –ve DNL,
the actual step value lies below the ideal step value.
3
Value in brackets for V
= 2.375 V–2.75 V.
4
External current required to overdrive internal V
.
5
I
, the circuit current, is the continuous current required to drive the digital core.
6
Guaranteed maximum by characterization.
7
I
is the total current required to supply all DACs including the V
REF
circuitry and the PLL circuitry.
8
All DACs on.
