Digital out, output low voltage, no load
The PIC12F1572 has a 5-bit resolution rail-to-rail DAC built-in (which is fairly unusual, almost all microcontrollers have ADC's but few have DAC's).

Rather than use Vdd (5v) as the high end of the DAC, you can choose to use the fixed reference FVR_buffer2 lead instead, which is by default 1.024v.  This, divided by the 32 steps of the DAC yields 0.032v per step.  So values sent to the DAC of 0-8 will give you 0.0 volts to 0.256 volts.
