• DAC Driver linearity above 3.6V
1. DAC Driver linearity above 3.6V
With 5V Vcc, the DAC driver linearity is poor when DAC output level is above Vcc-1V. At 5V,
DAC output for 1023 will be around 5V - 40mV.
Work around:
Use, when Vcc=5V, Vref below Vcc-1V
Or, when Vref=Vcc=5V, do not uses codes above 800.
