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 x 100 W into 4 O. 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.
