The LM4811 is a dual audio power amplifier designed for high-quality output in portable systems. It can deliver 105mW per channel of continuous average power into a 16Ω load with a 5V power supply and 0.1% THD+N.
This amplifier features a digital volume control with a range from +12dB to -33dB in 16 discrete steps, controlled via a two-wire interface. It also includes a "click and pop" suppression circuitry and requires no bootstrap capacitors or snubber networks, simplifying external component requirements.
The LM4811 is unity-gain stable and offers an externally controlled, active-high, micropower consumption shutdown mode, with a low shutdown current of 0.3 μA typical. It also incorporates an internal thermal shutdown protection mechanism.
Available in WSON and VSSOP surface mount packages, the LM4811 is suitable for applications such as cellular phones, MP3 players, CD/DVD players, PDAs, and other portable electronic devices.
