A precision analog component requires careful layout. The following list provides some insight into good layout practices.

• Bypass the VDD to ground with a low ESR ceramic bypass capacitor. The typical recommended bypass capacitance is 0.1-µF to 0.22-µF ceramic capacitor, with a X7R or NP0 dielectric.
• Place power supplies and REF bypass capacitors close to the pins to minimize inductance and optimize performance.
• Use a high-quality, ceramic-type NP0 or X7R for optimal performance across temperature, and a very low dissipation factor.
• The digital and analog sections must have proper placement with respect to the digital pins and analog pins of the DACx0501 devices. The separation of analog and digital blocks minimizes coupling into neighboring blocks, as well as interaction between analog and digital return currents.
