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.
Key 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. The LM4981 provides high quality audio reproduction with minimal external components. A ground referenced output eliminates the output coupling capacitors typically required to drive single-ended loads such as headphones. The ground reference architecture redu.
