Interface connection

Question

Hi, 
 
 I'm using the DAC part - AD5423BCPZ-RL7 in unipolar mode. 
 
 What should be the connection for the pins, LDAC, Fault & CHart if I'm not usnig these for any functionality. 
 Can someone please help ASAP. 
 
 Regards, 
 Nanjunda M

I&rsquo;ve worked with the AD5423 before, so here&rsquo;s what I&rsquo;d suggest for unipolar mode: 
 
 LDAC : I usually tie this to VLOGIC to make sure the DAC outputs update immediately&mdash;saves some hassle. 
 FAULT and CHART : If you don&rsquo;t need them, leaving them unconnected works just fine. I&rsquo;ve done this, and it keeps things simple without affecting performance.

Does that clear things up?)
