Part Number: LMH0397

Hi team,

My customer wants to know how to handle the SDI_OUT pin if they won't use it?

Could they leave it unconnected?

Thanks!

Hi Luke,

Yes. If they do not use SDI_OUT, they can leave SDI_OUT unconnected. To power down SDI_OUT, please request the customer to leave the SDI_OUT_SEL unconnected (internally pulled high) or pulled high externally with 1kOhm to VDD so that the SDI_OUT driver is powered down.

Regards,

Michael
