The CXAR4186/A is a mono, filter-free Class-D audio amplifier available in WLCSP1.5x1.5-9 or TDFN3x3-8 package. The default gains without the external input resistor is 27dB. Besides, the gain can be low down by external input resistance. CXAR4186A provides an Dynamic-RangeControl (DRC) function, and this function can low down the dynamic range for large input signal.CXAR4186 can provide maximun 15dB gain control. CXAR4186A can provide maximum 15dB gain decrease for non-clipping function, and this function can avoid output signal clipping. High PSRR and differential architecture provide increased immunity to noise and RF rectification. In addition to these features, a fast start-up time and small package size make the CXAR4186/A an ideal choice for portable devices. The CXAR4186/A is capable of driving 1.6W at 5V or 0.8W at 3.6V into 8W. It is also capable of driving 4W. The CXAR4186/A is designed with a Class-D architecture and operating with highly efficiency compared with ClassAB amplifier. It’s suitable for power sensitive application, such as battery-powered devices. The filter-free architecture eliminates the output filter, reduces the external component count, board area, and system costs, and simplifies the design. Moreover, the CXAR4186/A provides thermal and short circuit protection
