Texas Instruments LM4946SQ/NOPB
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 two-channel stereo signal and the third for a differential single-channel mono input. The LM4946 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 I
The LM4946 is designed for cellular phone, PDA, and other portable handheld applications. It delivers high quality output power from a surface-mount package and requires only seven external components in the OCL mode (two additional components in SE mode).
