MAX9879ERV+TCEP

Audio Amplifiers Overview

The MAX9879ERV+T is a stereo Class D audio subsystem with a DirectDrive headphone amplifier. It operates on a single supply of 2.7V to 5.5V and delivers up to 715mW into an 8Ω load at 3.7V. The integrated headphone amp provides 58mW into 16Ω. Key parameters include 0.04% THD+N for the speaker amp, 88% efficiency, and I2C control.

Audio Amplifiers Feature Summary

• Filterless Class D modulation with active emissions limiting reduces EMI without output filters.
• DirectDrive architecture eliminates DC-blocking capacitors for space-saving headphone outputs.
• Flexible input mixer supports user-defined modes with programmable preamplifier gains.
• Comprehensive click-and-pop suppression ensures quiet startup and shutdown transitions.

Audio Amplifiers Applications

• Cell Phones
• Portable Multimedia Players

Audio Amplifiers Procurement Notes

Verify the specific suffix 'TCEP' against official documentation, as standard listings typically use 'ERV+'. Confirm package type and temperature range match the datasheet specifications for the MAX9879 family before procurement.

Audio Amplifiers Selection Notes

Select this component for applications requiring high-efficiency stereo audio amplification in a compact form factor. The UCSP package minimizes board space, while the integrated headphone amplifier simplifies design by removing external coupling capacitors.

Audio Amplifiers Part Context

This device belongs to the MAX9879 series of stereo audio subsystems. It integrates a Class D power amplifier and a capacitor-less headphone amplifier into a single 30-bump UCSP package, designed for portable electronics requiring high performance and low power consumption.

Audio Amplifiers Replacement Considerations

Check for MAX9879 variants with different suffixes or packages. Ensure any substitute maintains the same UCSP footprint and electrical characteristics for direct integration.
