Description

The LM4845 is an audio power amplifier capable of delivering 500mW of continuous average power into a mono 8Ω bridged-tied load (BTL) with 1% THD+N, 25mW per channel of continuous average power into stereo 32Ω single-ended (SE) loads with 1% THD+N, or an output capacitor-less (OCL) configuration with identical specification as the SE configuration, from a 3.3V power supply.

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 or a three-wire SPI compatible interface that allows flexibility in routing and mixing audio channels. The LM4845 has three input channels: one pair for a two-channel stereo signal and the third for a single-channel mono input.
