LM4991, 3W Audio Power Amplifier
The LM4991 is a mono bridged audio power amplifier capable of delivering 3W of continuous average power into a 3Ω load with less than 10% THD when powered by a 5V power supply (Note 1).
To conserve power in portable applications, the LM4991’s micropower shutdown mode (ISD = 0.1µA, typ) is activated
LM4991 Features
* include thermal shutdown protection, unity-gain stability, and external gain set. Note 1: An LM4991LD that has been properly mounted to a circuit board will deliver 3W into 3Ω (at 10% THD). The other package options for the LM4991 will deliver 1.5W into 8Ω (at 10% THD). See the Application Informati
