Figure 3. Output Voltage vs Full-Scale Resistance

The user is free to connect another resistor value, but care should be taken not to exceed the maximum current

level on each of the DAC outputs as shown in the specifications section. Additionally, DAC output linearity will

degrade if the 1.2-V maximum output compliance is exceeded.
