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 bulky DC-blocking capacitors. The device delivers up to 80mW per channel into a 16Ω load with low 0.003% THD+N. It operates from a single 1.8V to 3.6V supply and consumes only 5mA of quiescent current. The internal gain is set to -2V/V. It features integrated click-and-pop suppression, independent shutdown controls, short-circuit protection, thermal-overload protection, and ±8kV ESD-protected outputs.

Audio Amplifiers Feature Summary

• DirectDrive architecture eliminates the need for large DC-blocking output capacitors by generating an internal negative supply to bias outputs at ground potential.
• Internally fixed gain configuration removes the requirement for external feedback networks, reducing component count.
• Integrated comprehensive click-and-pop suppression circuitry prevents audible transients during power-up and shutdown sequences.
• Independent left/right active-low shutdown controls allow optimized power savings in mixed-mode mono or stereo applications.

Audio Amplifiers Applications

• Notebook PCs
• Cellular Phones
• PDAs
• MP3 Players
• Smart Phones

Audio Amplifiers Procurement Notes

Verify the specific suffix +CAN against official documentation to confirm lead-free status and environmental compliance details. Confirm package type matches the required board space constraints. Ensure the ordering information aligns with the intended gain specification for the application design.

Audio Amplifiers Selection Notes

Select this component when minimizing board space is critical due to the elimination of external DC-blocking capacitors. Choose this part for designs requiring a fixed gain of -2V/V without external resistors. Consider its operation within the 1.8V to 3.6V voltage range and the need for independent channel shutdown capabilities.
