CXAR41320 is a differential input audio power amplifier circuit suitable for mobile phones and other portable audio devices with built-in speakers. It can provide stable output of 1W power for 8Ω load, and its total harmonic distortion and noise shall not exceed 1% under the condition of 5V power supply. CXAR41320 the bridge load structure greatly reduces the number of external components while providing high-quality audio power amplification, eliminating the need for external output coupling capacitors and bootstrap capacitors. CXAR41320 built-in standby circuit, when the SHUTDOWN pin is connected to the low level, the whole circuit works in standby mode, and the standby current does not exceed 100nA. CXAR41320 has built-in noise cancellation circuit, which can eliminate the clicking sound or poop sound during chip startup and shutdown. The gain can also be adjusted by an external resistor.
