General Description

The LM4946 is an audio power amplifier capable of delivering 540mW of continuous average power into a mono 8Ω bridged-tied load (BTL) with 1% THD+N, 35mW 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 specifications as the SE configuration, from a 3.3V power supply.

The LM4946 has three input channels: one pair for a twochannel stereo signal and the third for a differential singlechannel mono input.

The LM4946

Key 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 threewire SPI compatible interface that allows flexibility in routing and mixing audio channels. The LM4946 is designed for cellular phone, PDA, and other portable handheld.
