LM4851 Datasheet Integrated Audio Amplifier

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LM4851 Integrated Audio Amplifier System December 2002 LM4851 Integrated Audio Amplifier.

General Description

The LM4851 is an audio power amplifier system capable of delivering 1.1W (typ) of continuous average power into a mono 8Ω bridged-tied load (BTL) with 1% THD+N and 115mW (typ) per channel of continuous average power into stereo 32Ω BTL loads with 0.5% THD+N, using a 5V power supply.

The LM4851

Key Features

  • a 32 step digital volume control and eight distinct output modes. The digital volume control and output modes are programmed through a three-wire SPI serial control interface, that allows flexibility in routing and mixing audio channels. The LM4851 has 3 inputs: one pair for a two-channel stereo signal and the third for a singlechannel mono input. The LM4851 is designed for cellular phone, PDA, and other portable handheld.
