3.13.1. Audio amplifier sub system IC with 3D effect
Audio amplifier sub system IC is an audio power amplifier capable of delivering 500mW of
continuous average power into a mono 8Ω load, 25mW per channel of continuous average power
into stereo 32Ω single-ended (SE) loads. The LM4845 features a 32-step digital volume control and
eight distinct output modes. The digital volume control, 3D enhancement, and output modes
(mono/SE/OCL) are programmed through a two-wire I2C interface that allows flexibility in routing
and mixing audio channels.
