Just to close out this thread, I tested a 16F1708 (same family as 16F1709)
with compiler vs. 5.060 and it worked fine. Here is the test program:
Code:

#include <16F1708.h>
#fuses INTRC_IO, NOWDT
#use delay(clock=4M)

//==================================
void main(void)
{
int8 value;

setup_dac(DAC_VSS_VDD | DAC_OUTPUT2);  // Output on Pin A2

value = 0;

while(TRUE)
  {
   dac_write(value);
   value++;
   delay_us(10);
  }
}


Here is a scope photo. It shows a full-scale ramp. It's working.

Thank You very much, I will try your code and if it doesnt work, the problem must be my circuit around the PIC Smile
