The 6-bit DAC is 64-tap resistor ladder network which provides a selectable voltage reference for applications where voltage reference is needed. The 64-tap resistor ladder network divides the supply reference Vin into 64 voltage levels. A 6-bit digital signal input selects the output voltage level, which varies from Vin to Vin/64. Vin can be selected from two voltage sources, Vin1 and Vin2. The 6-bit DAC from a comparator is available as an on-chip internal signal only and is not available externally to a pin.
