With the values of tRC given in Table 1, tCSS0 is always
given by tDV + tDS. For different values of R or C, tRC
must be calculated to determine tCSS0.
Additionally, the maximum clock frequency is limited to
1
fCLK (max) =
鈥斺€斺€斺€斺€斺€斺€斺€斺€斺€斺€斺€斺€� .
2 x (tDO + tRC -15ns + tDS)
For example, with tRC = 15ns (5V 卤10% supply with
1k
pull-up), the maximum clock frequency is 2MHz.
Digital-to-Analog Section
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.)
