LM4839 Stereo 2W Audio Power Amplifiers

The LM4839 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+N, or 2.2W into 3Ω (Note 2) with less than 1.0% THD+N. Boomer ® audio integrated circuits were designed specifical.

LM4839 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, the LM4839LQ and LM4839MTE will deliver 2W into 4Ω. The LM4839MT will deliver 1.1W into 8Ω.
