TDF8591TH 2 × 100 W SE (4 Ω) or 1 × 310 W BTL (4 Ω) class-D amplifier Rev. 01 — 5 March 2008 Product data sheet 1. 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. 2.
