RECOMMENDED EXTERNAL COMPONENTS

Figure 35 Recommended External Components

Notes:

1.

Wolfson recommend using a single, common ground plane. Where this is not possible, care should be taken to

optimise split ground configuration for audio performance.

2.

Charge Pump fly-back capacitor C5 should be placed as close to WM8533 as possible, followed by Charge Pump

decoupling capacitor C1, then LINEVDD and VMID decoupling capacitors.

3.

Capacitor types should be chosen carefully. Capacitors with very low ESR are recommended for optimum

performance.
