DAC43608: Customer Questions

Kazuki Itoh

Part Number: DAC43608

Hi team,

Datasheet mentions A0 can be tied to VDD. It doesn't require pull up resistor, right? Is it just CMOS input? Just want to make sure just in case.
When some of DAC43608 VOUT is unused, is it OK to leave it open?

Regards,

Hi Itoh,

You can have pull up no issues, infact I recommend having may be 10k, otherwise also no issues. Its CMOS input

Unused VOUT's can be left floating.

Hi AK,

Thank you for quick response.

Why do you recommend having 10KOhm pull-up resistor while it's just CMOS input?

Hi,

Not required if you are shorting to device VDD.
