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