The LM49200 is a fully integrated audio subsystem with a stereo power amplifier capable of delivering 500mW of continuous average power per channel into 8Ω with 1% THD+N using a 3.3V supply. The LM49200 includes a separate stereo headphone amplifier that can deliver 35mW per channel into 32Ω.
The LM49200 has three input channels. A pair of single-ended inputs and a fully differential input channel. The LM49200 features a 32-step digital volume control on the input stage and an 8-step digital volume control on the headphone output stage.
The digital volume control and output modes are programmed through a two-wire I 2C compatible interface that allows flexibility in routing and mixing audio channels
