Audio Amp Headphone/Speaker 2-CH Stereo 2.2W Class-AB 28-Pin TSSOP EP T/R, LM4938MHX/NOPB, Texas Instruments

Описание

The LM4938 is a monolithic integrated circuit that provides DC volume control, and stereo bridged audio power amplifiers capable of producing 2W into 4? with less than 1.0% THD or 2.2W into 3? 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 4?. See Application Information sectionfor more information.Note 2: An LM4938MH that has been properly mounted to the circuit board and forced-air cooled will deliver 2.2W into 3?.
