PROGRAMMABLE INTERNAL REFERENCE
The reference can be sourced internally or externally under software control. If an external reference
voltage is applied to the REF pin, the device must be configured to accept this.
If an external reference is selected, the reference voltage input is buffered which makes the DAC
input resistance independent of code. The REF pin has an input resistance of 10M
and an input
capacitance of typically 55pF. The reference voltage determines the DAC full-scale output.
If an internal reference is selected, a voltage of 1.024V or 2.048 is available. The internal reference
can source up to 1mA and can therefore be used as an external system reference.
