NXP's class-D amplifiers IC creates concert quality car audio

NXP's new class D amplifier IC TDF8599 delivers higher efficiency and high quality audio. The new TDF8599 Class-D amplifier delivers maximum output power from 70 - 130 watts (250 watts mono). Class D configured amplifiers, which is basically switching amplifier or PWM amplifier delivers higher than 90% efficiencies, replacing high power consuming class AB amplifiers. The audio quality is also good in class D compared to class AB amplifiers

NXP claims, with an extremely high dynamic audio range, the new Class-D amplifiers transform the vehicle entertainment experience, delivering concert hall-like sound quality for best-possible audio enjoyment on the move. The TDF8599 amplifier is new addition to already existing portfolio of NXP's Class-D amplifiers.

Christian Seidel, Group Leader Hardware, Mechanics & Layout Audio System Engineering Group from Harman Becker Automotive Systems in Straubing, Germany said, "The TDF8599 series gives us the opportunity to dramatically reduce the power dissipation in our multichannel audio amplifiers and at the same time increase the sound quality to satisfy our customers' needs."

"With our new TDF8599 Class-D stereo amplifier family, we offer an outstanding audio experience while further driving down power consumption. We are creating the ideal technology platform to support next generation in-vehicle infotainment," said Dr. Tobias Helbig, Senior Director Audio Power in BL Car Entertainment Solutions, NXP Semiconductors. "As car manufacturers continue to identify new opportunities to improve the passenger experience, and integrate an increasing range of functionality into their latest vehicles, it's critical that in-car energy consumption is effectively and responsibly managed."

The TDF8599 family includes the TDF8599A and TDF8599B dual Bridge-Tied Load (BTL) car audio amplifiers comprising a dual NDMOS-Transistor output stage based on Silicon On Insulator (SOI) BCD MOS technology. The NXP TDF8599A can operate in either non-I2C-bus mode or I2C-bus mode. When in I2C-bus mode, DC load detection results and fault conditions can be easily read back to the device. Up to 15 I2C-bus addresses can be selected. All products are fully qualified according to the AEC-Q100 automotive quality standard.
