DAC5689 - unused pins ?

Lahatra RAKOTONDRAINIBE

Other Parts Discussed in Thread: DAC5689

Hello,

If B-channel data of DAC5689 is not used (I only need A channel data to optimise the I/Os interface between the FPGA and DAC).

Question : all unconnected pins DB(15..0) should be left open or connected to the ground ?

Thank you,

Regards,

Lahatra

Hi Lahatra,

There are internal pull down resistors on all data input pins(DA(15..0 & DB(15..0) ) so you can leave the unused DATA input pins floating.
