General description

The TDF8591TH is a high-efﬁciency class-D audio power ampliﬁer with low power

dissipation for application in car audio systems. The typical output power is 2

× 100 W

into 4

Ω.

The TDF8591TH 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 ampliﬁer operates over a wide supply voltage range from

±14 V

to

±29 V and consumes a low quiescent current.
