Product Summary
TDF8591TH/N1S is a high-efficiency class-D audio power ampli?er with low power dissipation for application in car audio systems. The TDF8591TH/N1S is available in an HSOP24 power package with a small internal heat sink. Depending on the supply voltage and load conditions, a small or even no external heat sink is required. The TDF8591TH/N1S operates over a wide supply voltage range from ±14V to ±29V and consumes a low quiescent current.
