Beskrivning
The LM4834 is a monolithic integrated circuit that provides
DC volume control, and a bridged audio power amplifier
capable of producing 1.75W into 4? with less than 1.0%
(THD). In addition, the headphone/lineout amplifier is capable of driving 70 mW into 32? with less than 0.1%(THD).
The LM4834 incorporates a volume control and an input
microphone preamp stage capable of driving a 1 k? 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.
