com LM4920 Ground-Referenced, Ultra Low Noise, Fixed Gain, 80mW Stereo Headphone Amplifier March 2006 LM4920 Ground-Referenced, Ultra Low Noise, Fixed Gain, 80mW Stereo Headphone Amplifier General Description The LM4920 is a ground referenced, fixed-gain audio power amplifier capable of delivering 80mW of continuous average power into a 16Ω single-ended load with less than 1% THD+N from a 3V power supply.
The LM4920 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-ended loads.
