MAX9710EUE+

Audio Amplifiers Overview

The MAX9710EUE+ is a stereo bridge-tied load (BTL) audio power amplifier manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single 4.5V to 5.5V supply and delivers up to 3W into a 3Ω load at 1% THD+N. Key electrical parameters include an industry-leading 100dB power-supply rejection ratio, ultra-low 0.005% total harmonic distortion plus noise, and a quiescent supply current of 7mA. The device features a low-power shutdown mode with 0.5μA current consumption, active MUTE functionality, and comprehensive click-and-pop suppression.

Audio Amplifiers Feature Summary

Audio Amplifiers Procurement Notes

Verify the specific suffix EUE against official documentation to confirm package type and RoHS compliance status. Confirm availability through authorized distributors as lead times may vary. Ensure the ordering code matches the exact pin configuration and thermal requirements for your design.

Audio Amplifiers Selection Notes

Select this component for applications requiring high-fidelity audio output from a single 5V supply. The BTL architecture eliminates the need for large DC-blocking capacitors. Consider the exposed pad thermal performance and layout requirements when designing for maximum power dissipation under continuous load conditions.

Audio Amplifiers Part Context

This part belongs to the MAX9710/MAX9711 family of 3W mono/stereo BTL audio power amplifiers. The MAX9710 variant provides stereo output channels, while the MAX9711 offers a mono configuration. Both share identical electrical characteristics and feature sets, differing primarily in channel count and pinout.

Audio Amplifiers Replacement Considerations

The MAX9711 serves as the mono-channel counterpart within the same product family. Verify pin compatibility and channel requirements before substitution. No other direct cross-model replacements are documented in the provided datasheet.

Audio Amplifiers FAQ

How does the device handle click-and-pop suppression?

The device uses an S-shaped waveform to slowly ramp the common-mode bias voltage during startup and actively drives outputs low during shutdown to minimize energy in the audio band.

What is the function of the BIAS pin?

The BIAS pin provides an internally generated, power-supply-independent 2.5V common-mode bias voltage referenced to ground, which sets the DC bias level for the audio outputs and supports click-and-pop suppression.
