LM4811 Dual-channel headphone amplifier circuit diagram
LM4811 is a dual channel headphone amplifier with 5V power supply. Each channel outputs 105mW continuous average power to drive 16Ω load. Total harmonic distortion plus noise (THD + N) is only 0.1%. LM4811 does not require bootstrap capacitor and buffer. It is qualified to low-power portable systems, cellular phones and the system MP3, CD, DVD players etc. LM4811 has an external control terminal. It has an effective high level shutdown mode to work in the micro-power. There is an internal thermal shutdown protection agency. LM4811 pinout is shown as the chart.
