SERIAL DATA OUTPUT
The serial-data output (SDO) is the internal shift register
output. For the DAC7654, the SDO is a driven output and
does not require an external pull-up. Any number of
DAC7654s can be daisy-chained by connecting the SDO
pin of one device to the SDI pin of the following device in
the chain, as shown in Figure 57.
DIGITAL TIMING
Figure 58 and Table 4 provide detailed timing for the digital
interface of the DAC7654.
DIGITAL INPUT CODING
The DAC7654 input data is in straight binary format. The
output voltage for single-supply operation is given by
Equation 1:
V
OUT
+ 2.5
N
65, 536
where N is the digital input code.
This equation does not include the effects of offset
(zero-scale) or gain (full-scale) errors.
The output for the dual supply operation is given by
Equation 2:
V
OUT
+ 5
N
65, 536
* 2.5
