2.4 Analog Speaker Output

The IS2062/64 SoC (except IS2064GM-0L3) supports the following speaker output modes:

Capless mode — Recommended for headphone applications in which capless output connection helps to save the BOM cost by avoiding a large DC blocking capacitor. Figure 2-7 illustrates the analog speaker output Capless mode.
Single-Ended mode — Used for driving an external audio amplifier, where a DC blocking capacitor is required. Figure 2-8 illustrates the analog speaker output Single-Ended mode.
