The PAM8124 is a 15W efficient, Class-D audio power amplifier for driving stereo speakers in a single-ended configuration; or a mono speaker in a bridge-tied-load configuration. The PAM8124 can drive stereo speakers (SE) as low as 4Ω. Due to the low power dissipation and high efficiency the device can be used without any external heat sink when playing music.
The gain of the amplifier is controlled by 2 gain selectable pins, offering 20dB, 26dB, 32dB, and 36dB gain selections.
