General description

The TDF8590TH 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

× 80 W

into 4

Ω.

The TDF8590TH 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.

I High efﬁciency

I Supply voltage from ±14 V to ±29 V

I Low quiescent current

I Usable as a stereo Single-Ended (SE) ampliﬁer or as a mono ampliﬁer in Bridge-Tied

Load (BTL)

I Fixed gain of 26 dB in SE and 32 dB in BTL

I High BTL output power: 160 W into 8 Ω, 120 W into 4 Ω

I Suitable for speakers in the range of 2 Ω to 8 Ω

I High supply voltage ripple rejection

I Internal oscillator or synchronized to an external clock

I Full short-circuit proof outputs across load and to supply lines

I Thermal foldback and thermal protection
