LM4981 Ground-Referenced, 80mW Stereo Headphone Amplifier with Digital Volume Control
General Description
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.
This allows the outputs to be biased about ground, thereby eliminating output-coupling capacitors typically used with normal single-end...
