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 ?.

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.

Features
