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.
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.
