Digitally Controlled Tone And Volume Circuit With Stereo Audio Power Amplifier, Microphone Preamp Stage And National 3D Sound

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 8 or 90 mW (typ) into 32 with less than 1.0% THD. In addition, a two input Microphone preamp stage, with Volume Control capable of driving a 1 k load is implemented on chip.
The LM4832 also 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 preamp stage, it is optimally suited to Multimedia monitors and desktop computer applications.
