With its audiophile-quality sound, the extremely robust TDF8599C Class-D amplifier is specifically designed for automotive applications. The solution is energy efficient and environmentally friendly as it produces little waste heat. With potent 48V sound power, the amplifiers allow high supply voltages enabling designers to increase the impedance of the load speakers at high output power. High impedance of the speakers enables compact speaker design, saving weight and cable diameters.
