  • FPGA extended speaker problem

    Guys, I am an FPGA beginner, and the development board used does not have a buzzer speaker; now there are audio pulses that can be generated, and there is an urgent need to add a buzzer or speaker that can make sounds. There are GPIO pin headers on the board, I don't know how to connect the external speakers. Do you have any opinions?

    Your question has nothing to do with Pro Audio/Sound Reinforcement. Suggest you find a forum that deals with FPGA.

        I found the answer,The audio signal is sent to the speaker after passing through the power amplifier. The common model of low-power audio amplifiers is LM386 TDA2822 (dual channel). Digital power is now more popular.
        High-power common power amplifier IC: TDA2030
