|
The LM4949 is a fully integrated audio subsystem designed for stereo cell phone applications. The LM4949 bines a 2.5W stereo Class D amplifier plus a separate 190mW stereo headphone amplifier, volume control, and input mixer into a single device. The filterless class D amplifiers deliver 1.19W/channel into an 8Ω load with < 1% THD+N from a 5V supply.
