The LM4838 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 (see Notes below).
Boomer audio integrated
circuits were designed specifically to provide high quality audio while requiring a minimum amount
of external components. The LM4838 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 LM4838 features an externally controlled, low-power consumption shutdown mode, and
both a power amplifier and headphone mute for maximum system flexibility and performance.
Note: When properly mounted to the circuit board, the
LM4838NJB, LM4838PWP, and LM4838NYC will deliver 2W into 4Ω. The LM4838PW and LM4838YZR will
deliver 1.1W into 8Ω. See section for more
Note: An LM4838NJB and LM4838PWP that have been properly
mounted to the circuit board and forced-air cooled will deliver 2.2W into 3Ω.
