LM49101 Datasheet Mono Class Ab Audio Subsystem

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LM49101Mono Class AB Audio Subsystem with a True Ground Headphone Amplifier and Earpiece Switch www.DataSheet4U.

General Description

The LM49101 is a fully integrated audio subsystem with a mono power amplifier capable of delivering 540mW of continuous average power into an 8Ω BTL speaker load with 1% THD+N using a 3.3V supply.

The LM49101 includes a separate stereo headphone amplifier that can deliver 44mW per channel into 32Ω loads using a 2.75V supply.

The LM49101 has four input channels.

Key Features

  • a 32.
  • step digital volume control on the input stage and an 8.
  • step digital volume control on the headphone output stage. The digital volume control and output modes, programmed through a two-wire I2C compatible interface, allows flexibility in routing and mixing audio channels. The LM49101 is designed for cellular phones, PDAs, and other portable handheld.
