产品简介

CXAR4188是一款单声道、高效率、无滤波器的D类音频放大器，可在WLCSP1.5x2-12和TQFN4x4-16封装中使用。CXAR4188是一款高效率的D级音频功率放大器，带有集成的G级升压转换器，可在低输出功率下提高效率。最多开3辆。6W输入4W扬声器（1%THD+N）。在85%的典型效率下，CXAR4188有助于延长播放音频时的电池寿命。当需要高输出功率时，内置的boost转换器为D级放大器产生5.75V的电源电压。这比直接连接到电池的独立放大器提供更大的音频输出。在音频输出功率较低的时期，boost转换器会关闭并将VBAT直接连接到类d放大器电源PVDD。这提高了整体效率。CXAR4188具有一个集成的低通滤波器，以提高射频抑制和降低DAC带外噪声，提高信噪比（SNR）

   产品概述 返回TOP

The CXAR4188 is a mono, high efficiency, filter-free Class-D audio amplifier and is available in WLCSP1.5x2- 12 and TQFN4x4-16 Package. The CXAR4188 is a high efficiency Class-D audio power amplifier with an integrated Class-G boost converter that enhances efficiency at low output power. It drives up to 3. 6W into an 4W speaker (1%THD+N).With 85% typical efficiency, the CXAR4188 helps extend battery life when playing audio. The built-in boost converter generates a 5.75V supply voltage for the Class-D amplifier when high output power is required. This provides a louder audio output than a stand-alone amplifier directly connected to the battery. During low audio output power periods, the boost converter deactivates and connects VBAT directly to the ClassD amplifier supply, PVDD. This improves overall efficiency. The CXAR4188 has an integrated low-pass filter to improve the RF rejection and reduce DAC out-of-band noise, increasing the signal-to-noise ratio(SNR)
