Figure 8-5. Decoupling of the AMC0x00D

Verify capacitors provide adequate effective capacitance under the applicable DC bias conditions experienced in

the application. Multilayer ceramic capacitors (MLCC) typically exhibit only a fraction of the nominal capacitance

under real-world conditions. Consider this factor when selecting these capacitors. This issue is especially acute

in low-profile capacitors, where the dielectric field strength is higher than in taller components. Reputable

capacitor manufacturers provide capacitance versus DC bias curves that greatly simplify component selection.

8.5 Layout

8.5.1 Layout Guidelines

The Layout Example section details a layout recommendation with the critical placement of the decoupling

capacitors (as close as possible to the AMC0x00D supply pins). This example also depicts the placement of

other components required by the device.
