The DAC converts digital values to analog voltages. The DAC has 12-bit resolution and is capa-
ble of converting 1 million samples per second. The output from the DAC can either be
continuous to one pin, or fed to two different pins using a sample and hold (S/H) circuitry. A sep-
arate low power mode is available, and the DAC can be gain and offset calibrated.
The output signal swing is defined by the reference voltage (VREF). The following sources are
available as VREF in the DAC:
The output voltage from a DAC channel is given as:
