NXP claims breakthrough Class-AB and Class-D audio amplifiers for start-stop systems
November 14, 2011 // Paul Buckley
NXP Semiconductors N.V. has introduced two new automotive audio amplifiers supporting energy-saving start-stop systems – the TDF8530 and TDF8546. The TDF8530 is an ultra-efficient quad-channel Class-D audio amplifier supporting the 6 V requirement for start-stop vehicles.
Drue Freeman, vice president, Global Automotive Sales and Marketing, NXP Semiconductors, said: By offering both Class-AB and Class-D options integrating a wide range of protections and advanced diagnostics, NXP is providing flexibility in designing reliable audio systems for energy-efficient vehicles. This is a great example of how we are using High Performance Mixed Signal technology to help our customers to drive efficiency in all types of vehicles, by achieving efficiency gains in sub-systems throughout the car.
If you drive any type of hybrid electric vehicle, you deserve a smooth in-car entertainment experience. With its excellent sound performance, automotive robustness and great energy efficiency, the NXP TDF8530 is the ideal choice for the high-performance audio solutions we are designing for the energy-conscious driver, said Yongmin Moon, principal research engineer in Hyundai Mobis Multimedia Core Tech Team.
The TDF8530 is the latest addition to NXPs broad portfolio of highly integrated, high-performance automotive Class-D amplifiers, which bring concert-hall quality sound to in-car entertainment systems. The quad channel Class-D amplifier is ideal for automotive head unit and sound system platforms. High-end home entertainment systems such as iPod docking stations can also benefit from the outstanding audiophile sound performance of the TDF8530. The new Class-D amplifier is also designed to support new application areas such as car ambient sound systems, which can create engine sounds for electric vehicles, for example, or active noise-cancellation systems.All news
