产品简介

CXAR4196是一款立体声全差分音频功率放大器，带有立体声AB级无盖耳机驱动器和LDO，采用TQFN5X5-32A引脚封装。功率放大器的内置增益设置可以最小化外部元件的数量。对于灵活的应用，增益可以通过增益控制管脚（GAIN0和gain1）设置为4阶、10、12、15.6和21.6dB。功率放大器的全差分结构提供了高的PSRR，提高了抗噪声和RF整流能力。CXAR4196功率放大器能够在VDD=5V时驱动2.4W到4W扬声器，无盖耳机驱动器可以在HVDD=3.3V到16w耳机时提供180mW，LDO的音频编解码器的最大驱动电流为120mA（3.3V）。CXAR4196提供热保护和过电流保护。无盖耳机驱动器消除了输出端的直流阻塞电容，节省了PCB空间。全差分功率放大器、无盖耳机驱动器和LDO的集成是VISTATM需求的最佳解决方案，可以降低BOM的总成本。

   产品概述 返回TOP

The CXAR4196 is a stereo fully differential audio power amplifier with stereo Class-AB cap-free headphone driver and LDO available in a TQFN5X5-32A pins package. The built-in gain setting at power amplifier can minimize the external component counts. For the flexible application, the gain can be set to 4-steps, 10, 12, 15.6, and 21.6dB by gain control pins (GAIN0 andGAIN1). The power amplifier’s fully differential architecture provides high PSRR, increased immunity to noise and RF rectification. The CXAR4196 power amplifiers are capable of driving 2.4W at VDD =5V into 4W speaker, the cap-free headphone drivers can provide 180mW at HVDD =3.3V into16W headphones, and the LDO has a maximum 120mA (3.3V) driver current for audio codec. The CXAR4196 provides thermal and over-current protections. The cap-free headphone driver eliminates the DC blocking capacitors at outputs and saves the PCB space. The integration of fully differential power amplifier, cap-free headphone driver, and LDO is a best solution for VISTATM requirement and it can lower the total BOM costs.
