AD8317 VSET PIN AS CONTROLLER MODE

Hi,

 

I'm trying to use AD8317 as controller mode.

I want set VSET pin target voltage using DAC but VSET pin is output voltage around 1V.

That voltage makes my target voltage different with DAC output.

There is no connection between VSET is not connected VOUT and GND.

 

I'm expecting VSET pin is pure input with floating.

Please support me what's wrong with VSET pin?

 

Regards,

Kooyong
