SINGLE +5 V SUPPLY OPERATION
For operation with a +5 V supply, the reference voltage should
be set between +1.0 V and +2.5 V for optimum linearity. Figure 30
shows an
headroom of the reference and DAC are both sufficient to support
a +5 V supply with ±5 V tolerance. AV
connected to the same supply. Separate bypassing to each pin
should be used.
