Overview

The LM4981 is a stereo, ground-referenced, output capacitor-less headphone amplifier capable of delivering 83mW of continuous average power into a 16Ω load with less than 1% THD+N while operating from a single 3V supply. The LM4981 features a new circuit technology that utilizes a charge pump to generate a negative reference voltage.
