The cxau4156 is a dual channel audio power amplifier. Each channel can provide 105mW average power (5V working voltage, 16 Ω load, thd + n = 0.1%), and the total harmonic distortion noise

The application circuit of cxau4156 is simple, only a few peripheral devices are needed; the output of cxau4156 does not need bootstrap capacitor or buffer network, which is encapsulated by MSOP and SOP, saving circuit area, so it is very suitable for the use of low-voltage and low-power applications such as mobile phones and various mobile devices; cxau4156 can enter the sleep mode through control, thus reducing power consumption
