.. LM4980 2 Cell Battery, 1mA, 42mW Per Channel High Fidelity Stereo Headphone Audio Amplifier for MP3 players July 2005 LM4980 2 Cell Battery, 1mA, 42mW Per Channel High Fidelity Stereo Headphone Audio Amplifier for MP3 players General Description The LM4980 is a stereo headphone audio amplifier, which when connected to a 3.0V supply, delivers 42mW to a 16Ω load with less than 1% THD+N. With the LM4980 packaged in the SD package, the customer benefits include low profile and small size. This package minimizes PCB area and maximizes output power. The LM4980 Features circuitry that significantly reduces output transients (“clicks” and “pops”) while driving headphones...
