产品简介

CXAR4189/A是一个提供内部增益控制的单片集成电路，它是一个立体声桥接音频功率放大器，能够以小于10%（1.0%）的THD+N将2.6W（1.9W）的功率转换为3W。通过控制Gain0和Gain1这两个增益设置管脚，放大器可以提供6dB、10dB、15.6dB和21.6dB的增益设置。内部增益设置的优点是可以减少元件和PCB面积。在CXAR4189/A中集成了depop电路和热关机保护电路，可在通电或关机模式操作期间降低pops和咔哒声。它还改善了电源关闭的弹出噪声，并保护芯片不受过温和短路故障的破坏。为了简化音频系统设计，CXAR4189将扬声器驱动的立体声桥接负载（BTL）模式和耳机驱动的立体声单端（SE）模式组合到一个芯片中，在该芯片中，SE/BTL输入控制引脚信号可以轻松地切换这两种模式。此外，多个输入选项用于便携式音频系统。CXAR4189A消除了输入选择和单端（SE）模式功能，简化了设计并节省了PCB空间
·低工作电流，6毫安
·改进的Depop电路消除了输出端的导通瞬变
·高PSRR
·内部增益控制，消除外部元件

   产品概述 返回TOP

CXAR4189/A is a monolithic integrated circuit, which provides internal gain control, and a stereo bridged audio power amplifiers capable of producing 2.6W (1.9W) into 3W with less than 10% (1.0%) THD+N. By controlling the two gain setting pins, Gain0 and Gain1, the amplifier can provide 6dB, 10dB, 15.6dB, and 21.6dB gain settings. The advantage of internal gain setting can be less components and PCB area. Both of the depop circuitry and the thermal shutdown protection circuitry are integrated in CXAR4189/A, that reduces pops and clicks noise during power up or shutdown mode operation. It also improves the power off pop noise and protects the chip from being destroyed by over temperature and short current failure. To simplify the audio system design, CXAR4189 combines a stereo bridge-tied loads (BTL) mode for speaker drive and a stereo single-end (SE) mode for headphone drive into a single chip, where both modes are easily switched by the SE/BTL input control pin signal. In addition, the multiple input selections are used for portable audio system. The CXAR4189A eliminates both input selection and single-end (SE) mode function to simplify the design and save the PCB space
