Detailed Design Procedure

In this application, the device is able to use both digital and analog inputs, routing this signal into the headphone outputs.

The internal LDO is being used in this application. External 1.8-V supply is used to power LDOIN, DVDD and IOVDD. AVDD is internally supplied by the LDO.

Decoupling capacitors should be used at all the supply lines. TI recommends using 0.1-µF and 10-µF capacitors for a better system performance.

Decoupling series capacitors must be used at the analog input and headphone output. The headphone output can be connected in single-ended mode with DC offset voltage while the decoupling series capacitor protects the speaker form the DC voltage. In addition the headphone output can be connected in a mono differential mode.

All grounds are tied together; route analog and digital paths are separated to avoid interference.
