The CXAR41314 is a differential input, direct output line driver/headphone amplifier. When powered by 5V, the device provides 125mW drive for a 32Ω headphone load. The IC can adjust the gain through an external resistor. The IC provides excellent THD N across the entire audio band.8Db嘉泰姆

The IC internal charge pump inverts the input power to produce a negative power supply. The output stage of the amplifier is powered by the input positive power supply and the charge pump output negative power supply, and the bipolar power supply makes the output bias at zero potential, eliminating the output coupling capacitor of large size and easy to introduce distortion.8Db嘉泰姆

There is no click/pop sound when the IC is powered on or off.8Db嘉泰姆
