APPENDIX 7
DAC BUFFERING
External buffering is needed on the ADV7194 DAC outputs.
The conguration in Figure 105 is recommended.
When calculating absolute output full-scale current and voltage
use the following equations:
VOUT = IOUT
× RLOAD
IOUT = (VREF
× K)/RSET
K = 4.2146 constant, VREF = 1.235 V
