Hello,

I am working on DAC7760 IC i am studding data sheet and found that it is very confusing on page number 32 there is "Table 6. Command and Register Map"

bellow that table there is note :

DAC8760 (16-bit version) shown. DAC7760 (12-bit version) contents are located in DB15:DB4. For DAC7760, DB3:DB0 are don't care bits when writing and zeros when reading.

But i want to set range in control register how it is possible if DB3:DB0 are don't care bits.?????

Regards,

Sagar

This only corresponds to the DAC Data register, so it will not affect the other registers. You can still use the control register normally.
