LM4832 Datasheet Digitally Tone/volume

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LM4832 Digitally Controlled Tone and Volume Circuit with Stereo Audio Power Amplifier, Microphone Preamp Stage and National 3D Sound February 1998 LM4832 Digitally Controlled Tone and Volume Circuit with Stereo Audio.

General Description

The LM4832 is a monolithic integrated circuit that provides volume and tone (bass and treble) controls as well as a stereo audio power amplifier capable of producing 250 mW (typ) into 8Ω or 90 mW (typ) into 32Ω with less than 1.0% THD.

In addition, a two input microphone preamp stage, with volume control, capable of driving a 1 kΩ load is implemented on chip.

The LM4832 also

Key Features

  • National’s 3D Sound circuitry which can be externally adjusted via a simple RC network. For maximum system flexibility, the LM4832 has an externally controlled, low-power consumption shutdown mode, and an independent mute for power and microphone amplifiers . Boomer ® audio integrated circuits were designed specifically to provide high quality audio while requiring few external components. Since the LM4832 incorporates tone and volume controls, a stereo audio power amplifier and a microphone pre.
