Typical Application (continued)
9.2.3 Application Curves
Figure 27 shows the output voltage vs code of this design, while Figure 28 shows the output error vs code. Keep
in mind that the error gets worse as the output code increases because the contribution of the gain error
increases with code.

10 Power Supply Recommendations
These devices can operate within the specified supply voltage range of 2.7 V to 5.5 V. The power applied to
AVDD should be well-regulated and low-noise. In order to further minimize noise from the power supplies, a
strong recommendation is to include a pair of 100 pF and 1 nF capacitors and a 0.1 μF to 1 μF bypass capacitor.
The current consumption of the AVDD pin, the short-circuit current limit, and the load current for these devices
are listed in the Electrical Characteristics table. Choose the power supplies for these devices to meet the
aforementioned current requirements.
