Audio Amplifiers datasheet and documents for MAX9877ERP+

MAX9877ERP+

Audio Amplifiers Overview

The MAX9877ERP+T is a mono audio subsystem integrating a Class D speaker amplifier and a stereo DirectDrive headphone amplifier. It operates on a single supply voltage ranging from 2.7V to 5.25V. The device delivers up to 725mW into an 8Ω load with 87% efficiency. Key electrical parameters include a quiescent current of 10mA, shutdown current of 22µA maximum, and input resistance varying by gain setting. It features I2C control, hardware/software shutdown, and click-and-pop suppression.

Audio Amplifiers Feature Summary

Filterless Class D architecture with active emissions limiting for low EMI
DirectDrive headphone amplifier eliminates DC-blocking capacitors
I2C interface with user-defined input modes and volume control
Comprehensive protection including thermal and current limits

Audio Amplifiers Applications

Cell phones
Portable multimedia players

Audio Amplifiers Procurement Notes

Verify the specific suffix 'ERP' against official documentation to confirm package type and die coating specifications. Ensure the ordering code matches the required temperature range and packaging format. Cross-reference the manufacturer's latest datasheet revision to confirm pinout compatibility and any potential design-in changes before finalizing procurement.

Audio Amplifiers Selection Notes

Select this component when space constraints require a combined speaker and headphone solution. The filterless Class D design reduces external component count compared to traditional topologies. Consider the DirectDrive feature if eliminating large output capacitors is necessary for board height reduction. Verify that the I2C interface aligns with the system controller capabilities.

Audio Amplifiers Part Context

This part belongs to the MAX9877 family of low RF susceptibility audio subsystems. It combines high-efficiency amplification with direct-drive capabilities in a compact WLP package. The series is designed for portable electronics requiring high performance in minimal space.
