MAX9702EUI+T

Audio Amplifiers Overview

The MAX9702EUI+T is a stereo audio amplifier integrating a Class D speaker stage and a DirectDrive Class AB headphone driver. It delivers up to 1.8W into 4Ω or 1.1W into 8Ω at 5V. The device operates on a single supply from 2.5V to 5.5V with a low-power shutdown current of 0.1µA. It features spread-spectrum modulation for EMI reduction, I²C programmable gain up to +21dB, and integrated click-and-pop suppression. The component is housed in a 28-pin thin QFN-EP package.

Audio Amplifiers Feature Summary

• Integrates a filterless Class D speaker amplifier and a DirectDrive Class AB headphone amplifier on a single chip.
• Utilizes spread-spectrum modulation to reduce electromagnetic interference without external output filters.
• Features an I²C interface for programmable gain, mute, mono/stereo selection, and mode switching.
• Includes comprehensive protection mechanisms such as short-circuit and thermal-overload safeguards.

Audio Amplifiers Applications

• Cellular phones
• Notebook PCs
• PDAs
• Handheld gaming consoles

Audio Amplifiers Procurement Notes

Verify the specific suffix 'EUI+T' against official documentation to confirm the tape-and-reel packaging format and lead-free status. Ensure the ordering code matches the exact pin configuration and temperature range specifications required for the design. Cross-reference the manufacturer's latest datasheet revision to confirm availability and any potential obsolescence notices.

Audio Amplifiers Selection Notes

Select this component when a compact solution is needed that combines both speaker and headphone amplification. It is suitable for designs requiring high efficiency in speaker mode and low distortion in headphone mode. Consider the I²C control requirements for gain adjustment and the thermal management needs associated with the exposed pad package.

Audio Amplifiers Part Context

This part belongs to the MAX9702 family of audio power amplifiers manufactured by Analog Devices Inc./Maxim Integrated. It represents a second-generation spread-spectrum modulation technology designed to eliminate the need for bulky output filters in Class D applications while maintaining high audio fidelity.
