LMX2594: RFoutB bias

Bert De Mulder

Part Number: LMX2594

Hi, in my application I only need one output (RFoutA) and will disable the second output. Is it possible to remove the bias circuit on port B if that amplifier is disabled, and just leave the pins open?

I am working on a dual-layer board so any space I can gain helps me in the layout work.

Thanks!

    Bert,

    Yes.  If you do not need the second output, then don't waste precious real estate on the board to route it.  For RFoutA, it is critical to get the pull-up as close to the device as possible, so if not routing unneeded features helps, then by all means do this.  

    Regards,
