SPEAKER IN STM32H563ZIT6

HI, Does the STM32H563ZIT6 have built-in capability to directly convert this digital data to an analog signal for speakers without using an external CS43L22 DAC (Digital-to-Analog Converter)?

You need to use DAC and then amplify it with an external audio amplifier like TS4872 to drive a speaker.
