DIGITAL TIMING
Figure 3 and Table II provide detailed timing for the digital
interface of the DAC7613.
DIGITAL INPUT CODING
The DAC7613 input data is in Straight Binary format. The
output voltage is given by the following equation:
( ) _{VOUT = VREFL +}
V_REFH – V_REFL
4096
•N
(1)
where N is the digital input code. This equation does not
include the effects of offset (zero-scale) or gain (full-scale)
errors.
