CXA3813N
Description
The CXA3813N is a headphone amplifier and 2-channel stereo audio line amplifiers IC. Each amplifier has a
fixed gain and mute function.
Pop noise of 2-channel stereo audio line amplifiers is free at power on/off and Mute.
1-channel stereo audio line amplifier has 2 stereo input multiplexer.
The CXA3813N is suitable for a wide range of consumer audio applications, such as portable A/V players, set-
top boxes, and digital televisions. The device is offered in a space saving 24pin SSOP package.
