产品概述
The LM4938 is a monolithic integrated circuit that provides DC volume control, and stereo
bridged audio power amplifiers capable of producing 2W into 4Ω with less than 1.0% THD or 2.2W into
3Ω with less than 1.0% THD. Boomer audio integrated circuits were designed specifically to provide high quality audio
while requiring a minimum amount of external components. The LM4938 incorporates a DC volume
control, stereo bridged audio power amplifiers and a selectable gain or bass boost, making it
optimally suited for multimedia monitors, portable radios, desktop, and portable computer
applications.The LM4938 features an externally controlled, low-power consumption shutdown mode, and
both a power amplifier and headphone mute for maximum system flexibility and performance.Note 1: When properly mounted to the circuit board,
LM4938MH will deliver 2W into 4Ω. See Application Information section for more information.Note 2: An LM4938MH that has been properly mounted to
the circuit board and forced-air cooled will deliver 2.2W into 3Ω.
