LM4938 Stereo 2W Audio Power Amplifiers

The LM4938 is a monolithic integrated circuit that provides DC volume control, and stereo bridged audio power amplifiers capable of producing 2W into 4Ω (Note 1) with less than 1.0% THD or 2.2W into 3Ω (Note 2) with less than 1.0% THD. Boomer ® audio integrated circuits were designed specifically to.

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 Exposed-DAP package P
