With the values of t
RC
given in Table 1, t
CSS0
is always
given by t
DV
+ t
DS
. For different values of R or C, t
RC
must be calculated to determine t
CSS0
.
Additionally, the maximum clock frequency is limited to
1
f
CLK
(max) = ————————————— .
2 x (t
DO
+ t
RC
-15ns + t
DS
)
For example, with t
RC
= 15ns (5V ±10% supply with
1k
pull-up), the maximum clock frequency is 2MHz.
Digital-to-Analog S ec tion
Figure 8 shows a simplified circuit diagram for one of
the DACs and the output amplifier.
A segmented scheme is used to improve linearity,
whereby the two MSBs of the 12-bit data word are
decoded to drive the three switches, SA, SB, and SC.
The remaining ten bits drive the switches S0 through S9
in a standard R-2R ladder configuration.
Each of the switches, SA, SB, and SC, steers 1/4 of the
total reference current with the remaining 1/4 passing
through the R-2R section.
The output amplifier and feedback resistor perform the
current-to-voltage conversion, giving the following:
VOUT_ = -D x VREF_,
where _ denotes A or B, and D is the fractional representa-
tion of the digital word. (D can be set from 0 to 4095/4096.)
