MAX4411BEBE

Audio Amplifiers Overview

The MAX4411BEBE is a fixed-gain, stereo headphone amplifier designed for portable equipment where board space is at a premium. It utilizes a patented DirectDrive architecture to produce ground-referenced outputs from a single supply, eliminating the need for bulky DC-blocking capacitors. The device features an internal gain of -2V/V and operates on a single 1.8V to 3.6V supply. It delivers 80mW per channel into a 16Ω load with low distortion (0.003% THD+N). Key electrical parameters include a quiescent current of 5mA, high power supply rejection ratio (86dB at 217Hz), and ±8kV ESD protection on amplifier outputs.

Audio Amplifiers Feature Summary

• DirectDrive architecture eliminates DC-blocking capacitors and reduces component height
• Fixed internal gain of -2V/V removes requirement for external feedback network
• Ground-referenced outputs prevent DC-bias voltages on headphone ground pins
• Integrated click-and-pop suppression ensures quiet startup and shutdown

Audio Amplifiers Applications

• Notebook PCs
• Cellular Phones
• MP3 Players
• Portable Audio Equipment

Audio Amplifiers Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status as indicated in official documentation. Check for obsolescence notices or lifecycle changes prior to procurement. Ensure packaging specifications match design requirements. Validate part number suffixes against official datasheets to confirm correct gain configuration.

Audio Amplifiers Selection Notes

Select this component for designs requiring minimal external passive components in audio paths. Consider the fixed -2V/V gain when determining signal levels. Evaluate the 1.8V to 3.6V operating range against system battery profiles. Assess thermal performance given the 80mW output capability. Verify package availability for the specific footprint required by the PCB layout.

Audio Amplifiers Part Context

The MAX4411 series belongs to Maxim Integrated's portfolio of low-power audio amplifiers optimized for mobile devices. It shares architectural similarities with the MAX4410 but offers fixed gain options to simplify circuit design. The DirectDrive technology distinguishes it from traditional Class AB amplifiers that require large coupling capacitors. This family targets applications demanding high sound quality within strict size and power constraints.
