LM4842 Datasheet (National Semiconductor)

LM4842, Stereo 2W Amplifiers

The LM4842 is a monolithic integrated circuit that provides DC volume control, and stereo bridged audio power amplifiers capable of producing 2W into 4Ω (Note 1) or 2.2W into 3Ω (Note 2) with less than 1.0% THD+N.

Boomer ® audio integrated circuits were designed specifically to provide high quality

LM4842 Features

* an externally controlled, low-power consumption shutdown mode (Shutdown Low), and both a power amplifier and headphone mute for maximum system flexibility and performance. Note 1: When properly mounted to the circuit board, the LM4842MH will deliver 2W into 4Ω. The LM4842MT will deliver 1.1W into 8Ω
