3.4 Analog Speaker Output

The BM83 module supports the following analog speaker output modes:

  • Capless mode – recommended for headphone applications in which capless output connection helps to save the Bill of Materials (BOM) cost by avoiding a large DC blocking capacitor. The following figure illustrates the analog speaker output in Capless mode.

  • Single-Ended mode – used for driving an external audio amplifier where a DC blocking capacitor is required. The following figure illustrates the analog speaker output in Single-Ended mode.
