... LTC1655/LTC1655L U U APPLICATIONS INFORMATION Rail-to-Rail Output Considerations In any rail-to-rail DAC, the output swing is limited to voltages within the supply range. If the DAC offset is negative, the output for the lowest codes limits shown in Figure 1b. Similarly, limiting can occur near full-scale when the REF pin is tied ...
