CXAR41315 Adjusting the gain through an external resistor 125mW Output-free coupling capacitor Differential input can directly output Stereo line driver Headphone amplifier Wide power supply working range Minimum support 1.6V operation Internal charge pum

The CXAR41315 is a headphone amplifier with differential input and direct output. When powered at 4.2V, the device provides 125mW drive for a 32Ω headphone load. The IC can adjust the gain through an external resistor. The IC has a wide power supply operating range and supports a minimum of 1.6V operation.

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.

There is no click/pop sound when the IC is powered on or off.
