TI公司的TAS5404-Q1是用于汽车音响主机的四路D类音频放器,四路模拟输入,四路BTL输出,每路能从14.4V电源中向4欧姆负载连续提供26W输出或向2欧姆负载连续提供45W输出,THD+N小于1%,75dB PSRR.每路增益为12 dB, 20 dB, 26 dB, 32 dB.本文介绍了TAS5404-Q1主要特性,框图和主要应用电路及其材料清单,汽车四路D类放大器参考设计TIDA-00573主要特性,框图,电路图,材料清单和汽车音响主机框图与主要指标.
The TAS5404-Q1 device is a four-channel class-D audio amplifier designed for use in automotive head units. The TAS5404-Q1 device provides four channels at 20 W continuously into 4 Ω at less than 1% THD+N from a 14.4-Vdc supply when used with the application circuit. The input is configured as an analog single-ended interface. The patented PWM topology of the device provides dramatic improvements in efficiency and audio performance over traditional linear amplifier solutions. The improvement in efficiency and audio performance reduces the power dissipated by the amplifier by a factor of ten under typical music playback conditions. The device incorporates all the required functions required by the OEM application. The built-in load diagnostic functions for detecting and diagnosing disconnected speakers help reduce test time during the manufacturing process.

汽车四路D类放大器参考设计TIDA-00573
The TIDA-00573 reference design provides a Class D based amplifier solution that allows it to be evaluated in the form factor of a typical Class AB amplifier.  The design is optimized to mitigate thermals associated with audio amplifiers and to minimize switching noises associated with Class D amplifiers.  This design is comprised of two parts.  The 1st highlights the audio amplifier module while the 2nd highlights the circuitry needed to incorporate it into a base board.  The pair of boards allows stand-alone performance testing of the design.
