11 Layout
11.1 Layout Guidelines
- All Power Supply terminals should be bypassed to ground with a low ESR ceramic bypass capacitor. The typical recommended bypass capacitance is 10-µF ceramic with a X7R or NP0 dielectric.
- To minimize interaction between the analog and digital return currents, the digital and analog sections should have separate ground planes that eventually connect at some point.
- To reduce noise on the internal reference, a 4.7-µF capacitor is recommended between the REF_CMP and GND.
- A high-quality ceramic type NP0 or X7R is recommended for its optimal performance across temperature, and very low dissipation factor.
