NOTES
1Typicals represent average readings at +25
°C.
2V
REFH can be any value between GND and V DD, for the AD8804 VREFL can be any value between GND and VDD.
3Guaranteed by design and not subject to production test.
4Digital Input voltages V
IN = 0 V or VDD for CMOS condition. DAC outputs unloaded. P DISS is calculated from (IDD × VDD).
5Measured at a V
OUT pin where an adjacent VOUT pin is making a full-scale voltage change (f = 100 kHz).
6See timing diagram for location of measured values. All input control voltages are specified with t
R = tF = 2 ns (10% to 90% of VDD) and timed from a voltage level of
1.6 V.
Specifications subject to change without notice.
