Description

The LM4834 is a monolithic integrated circuit that provides DC volume control, and a bridged audio power amplifier capable of producing 1.75W into 4W with less than 1.0% (THD). In addition, the headphone/lineout amplifier is capable of driving 70 mW into 32W with less than 0.1%(THD). 

The LM4834 incorporates a volume control and an input microphone preamp stage capable of driving a 1 kW load impedance. Boomer® audio integrated circuits were designed specifically to provide high quality audio while requiring a minimum amount of external components in surface mount packaging. The LM4834 incorporates a DC volume control, a bridged audio power amplifier and a microphone preamp stage, making it optimally suited for multimedia monitors and desktop computer applications. 

The LM4834 features an externally controlled, low-power consumption shutdown mode, and both a power amplifier and headphone mute for maximum system flexibility and performance.
