DAC7624/7625
DIGITAL TIMING
Figure 3 and Table II provide detailed timing for the digital
interface of the DAC7624 and DAC7625.
DIGITAL INPUT CODING
The DAC7624 and DAC7625 input data is in straight binary
format. The output voltage is given by the following equa-
tion:
where N is the digital input code. This equation does not
include the effects of offset (zero-scale) or gain (full-scale)
errors.
