2.12.2 Single End Output Configuration
Single end audio output connects audio output of the IS2083 internal CODEC to external analog audio amplifier input with a coupling capacitor. To prevent pop noise during CODEC power-on and -off, configure a GPIO pin to an enable function to control the external analog audio amplifier. The following figure illustrates the audio output connection from the IS2083 to external audio amplifier.
- Set the “Speaker Output” function as Single End External Amp.
- Set the “CODEC Type” as
Internal.
The following figure illustrates the GUI tool configuration for single end output to external audio amplifier on the CODEC Setup page.
The following figure is an example on how to configure a GPIO pin to an Enable pin of the external analog audio amplifier.
- Set the “Speaker Output” function as Single End Speaker Output.
- Set the “CODEC Type” as
Internal.
The following figure illustrates the GUI tool configuration for single end speaker output on the CODEC Setup page.
