Automotive External Amplifier

Описание:
The PMP11769 reference design is a complete solution for a 700W automotive audio amplifier. The boost converter provides 36.0V @ 10.0A continuous / 20.0A peak from an input voltage of 9 .. 16V. It contains two Class-D amplifiers which provide 2x 175W @ 4 Ohm load (left & right channel) and 1x 350W @ 2 Ohm (subwoofer).The design is well suited for car audio external amp applications due to its thin profile and high power output.
Возможности:

Easily integrated into automotive systems with 50V load dump and integrated protection system Ultra-HD audio for best quality sound for any integrated Class-D amplifier 100kHz bandwidth, which enables support for high resolution audio files and formats Low noise, which eliminates the "hiss" or "buzz" sounds

The TIDA-00743 reference design is a small module designed for evaluation of a digital-input class-D audio amplifier in a system which has been designed for a typical class AB audio power amplifier module. This design demonstrates the reduction in power dissipation that a class D amplifier provides. This design demonstrates how 2.1 MHz operation of a TAS6424-Q1 enables a compact power amplifier solution.
Возможности:

Audio output power: 21W per channel at 1% THD+N Meets automotive CISPR25 Class-5 EMI requirements Wide power supply voltage range of 4.5V to 18V 40V load dump protection Small size: 42.3mm x 53.5mm
