Difference between Rail to Rail DAC vs Single Supply?

gonna have some time this week to work on things again..

wondering if you made any headway on your DAC output Crossroads??

I saw you had started a DAC thread..where it seems you guys worked through alot fo things.. wondering if any of that new stuff will apply to the sample code I was suppose to try?

#include <SPI.h>  // check the format of that
int dataX;
byte DAC_SS = 9;
void setup(){
  pinMode(10, OUTPUT);
  pinMode (DAC_SS, OUTPUT);
  SPI.begin();
  // other setup stuff
}  // end setup
void loop(){
  for (dataX = 0; dataX < 0x1000; dataX = dataX+150){ // play with dataX+1 part
    SPI.transfer (highByte (dataX) );  // you will have your data as int's, from 0x0000 to 0x0FFF, this sends  the 0x0F part
    SPI.transfer (lowByte (dataX) );   // and this sends out the remaining FF part
    digitalWrite (DAC_SS, LOW);
    digitalWrite (DAC_SS, HIGH);
    //delayMicroseconds(13); // play with this 
  }
  for (dataX = 0x0FFF; dataX >= 0; dataX = dataX-150){ // play with dataX-1 part
    SPI.transfer (highByte (dataX) );  // you will have your data as int's, from 0x0000 to 0x0FFF
    SPI.transfer (lowByte (dataX) );
    digitalWrite (DAC_SS, LOW);
    digitalWrite (DAC_SS, HIGH);
    //delayMicroseconds(13); // play with this 
  }
}//end void loop

this was the last version I had tried to use...

Thanks
