MAX4411BEBE-T

Audio Amplifiers Overview

The MAX4411BEBE-T is a fixed-gain, stereo headphone amplifier designed for portable equipment. It utilizes DirectDrive architecture to produce ground-referenced outputs from a single supply, eliminating DC-blocking capacitors. The device features an internal gain of -2V/V and delivers 80mW per channel into 16Ω loads. Operating on a 1.8V to 3.6V single supply, it draws 5mA quiescent current. Key specifications include 0.003% THD+N, 86dB PSRR at 217Hz, and ±8kV ESD protection on outputs.

Audio Amplifiers Feature Summary

• DirectDrive architecture generates ground-referenced outputs without bulky DC-blocking capacitors
• Fixed internal gain of -2V/V eliminates external feedback networks
• Integrated click-and-pop suppression prevents audible transients during power-up and shutdown

Audio Amplifiers Applications

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

Audio Amplifiers Procurement Notes

Verify the specific suffix BEBE against official Analog Devices documentation to confirm package type and temperature range. Ensure compatibility with single-supply operation between 1.8V and 3.6V. Confirm that the fixed -2V/V gain meets system requirements without external resistors. Check for RoHS compliance status in the latest datasheet revision.

Audio Amplifiers Selection Notes

Select this component when board space is limited and capacitor-free headphone driving is required. The fixed -2V/V gain suits applications needing moderate amplification without external components. Consider the 5mA quiescent current for battery life constraints. Verify that the 80mW output power matches the connected headphone impedance and volume requirements.

Audio Amplifiers Part Context

The MAX4411 series belongs to Maxim Integrated's portfolio of audio amplifiers optimized for mobile devices. This family emphasizes low component count and high sound quality in small packages. The MAX4411B variant specifically provides a -2V/V gain setting, distinguishing it from the -1.5V/V MAX4411A version within the same architectural framework.

Audio Amplifiers Replacement Considerations

MAX4411AEUE-T offers identical functionality with a -1.5V/V gain instead of -2V/V. MAX4410EUD+T provides similar DirectDrive capabilities but requires verification of gain and package differences. Cross-reference pinouts and thermal characteristics before substitution.
