Product data sheet

1. 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.

2. Features

I Zero dead time switching

I Advanced output current protection

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
