The TMS8609F is a class-D audio power amplifier with analog input and high-power efficiency for driving two bridged-tied stereo speakers with up to 10W/8Ω (per channel). Higher than 90% efficiency making the TMS8609F eliminate the need for an external heat sink when playing music.

The TMS8609F integrated spread spectrum modulation (SSM) to avoid EMI/EMC interference which will eliminate to use huge and expensive LPF (Low Pass Filter) to save the PCB area and BOM cost.

The programmable soft clipping power limit (SCPL) limits the maximum output voltage to allows adjustment of the maximum output power without signal clipping for enhanced speaker protection and audio quality.

The TMS8609F features over current protection, short circuit protection and over temperature protection to fully protect the chip to be damaged.

The TMS8609F is available in TSSOP-28L package with exposed thermal pad.
