All power supply pins should be bypassed to ground with a low-ESR ceramic bypass capacitor. The typical recommended bypass capacitor has a value of 10-µF and is 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 pin and ground.
A high-quality ceramic type NP0 or X7R capacitor is recommended because of the optimal performance across temperature very-low dissipation factor of the capacitor.
The digital and analog sections should have proper placement with respect to the digital pins and analog pins of the AMC7836 device (see Figure 122). The separation of analog and digital blocks allows for better design and practice as it ensures less coupling into neighboring blocks and minimizes the interaction between analog and digital return currents.
