Digitally Controlled Tone and Volume Circuit with Stereo Audio Power Amplifier, Microphone Preamp Stage and National 3D Sound
LM4832
Digitally Controlled Tone and Volume Circuit with Stereo
Audio Power Amplifier, Microphone Preamp Stage and
National 3D Sound
General Description
The LM4832isa monolithic integrated circuit that provides
volume and tone (bass and treble) controlsas wellasa
stereo audio power amplifier capableof producing 250 mW
(typ) into 8Ωor90 mW (typ) into 32Ω with less than 1.0%
THD.In addition,a two input microphone preamp stage, with
volume control, capableof drivinga1kΩ loadis imple-
mentedon chip.
The LM4832 also features National’s 3D Sound circuitry
which canbe externally adjustedviaa simple RC network.
For maximum system flexibility, the LM4832 hasan exter-
nally controlled, low-power consumption shutdown mode,
andan independent mutefor power and microphone ampli-
fiers.
Boomer® audio integrated circuits were designed specifically provide high quality audio while requiring few external
components. Since the LM4832 incorporates tone and vol-
ume controls,a stereo audio power amplifier anda micro-
phone preamp stage,itis optimally suitedto multimedia
monitors and desktop computer applications.
