AUDIO POWER AMPLIFIER
■ DESCRIPTION
The AA4838 is a monolithic integrated circuit that provides DC volume control, and stereo
bridged audio power amplifiers capable of producing 2W into 4Ωwith less than 1.0% THD or
2.2W into 3 Ω with less than 1.0% THD. The audio integrated circuits were designed
specifically to provide high quality audio while requiring a minimum amount of external
components. The AA4838 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, and desktop and portable computer applications. The AA4838
features an externally controlled, low-power consumption shutdown mode, and both a power
amplifier and headphone mute for maximum system flexibility and performance.
■ FEATURES
• DC volume control interface.
• System beep detects.
• Stereo switchable bridged/single-ended power amplifiers
• Selectable internal/external gain or bass boost
• “Click and pop” suppression circuitry
• Thermal shutdown protection circuitry
■ APPLICATIONS
• Portable and desktop computers
• Multimedia monitors
• Portable radios, PDAs, and portable TVs
