NXP Releases Unique Class-D Amplifier Pushing Car Stereo Sound Into New Dimensions

Industry's First Class-D Amplifier TDF8599C Offers Supply Voltages up to 48V for Concert Hall-Like Sound Solutions in the Car

EINDHOVEN, THE NETHERLANDS--(Marketwire - Aug 28, 2012) -   NXP Semiconductors N.V. (NASDAQ: NXPI) today announced the TDF8599C, a new automotive stereo Class-D amplifier which targets sound systems in premium cars where high power output and efficiency are required. The device offers a supply voltage range up to 48V. This enables extremely high output power and the flexibility for sound designers to drive high-ohmic load speakers. Such speakers can be lighter, smaller and more cost efficient, resulting in vibrant automotive sound for the best sensory experience in the car.

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.
