illustrate

The LM4980 is a stereo headphone audio amplifier that provides 42mW to 16 when connected to a 3.0V power supply Load less than 1% THD + N In the LM4980 package in SD package, customer benefits include low profile and small size. This package reduces PCB area and maximizes output power.

The LM4980 features circuits that greatly reduce the output transients ("click" and "snap") of the headset when the device is turned on and off while driving, eliminating the need for expensive external additional circuits. The LM4980 also includes an externally controlled low-power, low-active-down mode and thermal shutdown. Boomer audio power amplifiers are designed to use few external components and provide high quality output power in a surface mount package.
