11.1 Layout Guidelines
A precision analog component requires careful layout, the list below provides some insight into good layout practices.
- Bypass all power supply pins to ground with a low ESR ceramic bypass capacitor. The typical recommended bypass capacitance is 0.1- to 0.22-µF ceramic 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 its optimal performance across temperature, and very low dissipation factor.
- The digital and analog sections must have proper placement with respect to the digital pins and analog pins of the DACx0508 device. The separation of analog and digital blocks minimizes coupling into neighboring blocks, as well as interaction between analog and digital return currents.
