Diodes – 2 x 15W Stereo Class-D Audio Power Amplifier

The PAM8124 is a high-efficiency, Class-D audio power amplifier for driving stereo speakers in a single-ended (SE) configuration (2x15W) or a mono speaker in a bridge-tied-load (BTL) configuration (30W).

It can drive stereo speakers with impedance as low as 4©. Due to its low power dissipation and high efficiency, up to 95%, the PAM8124 can be used without any external heat sink when playing music.

The gain of the amplifier is controlled by two gain selection pins, offering 20dB, 26dB, 32dB, and 36dB gain selections.

The PAM8124 is available in a TSSOP-24EP package.
