MAX98311EWL+T

Audio Amplifiers Overview

The MAX98311EWL+T is a mono Class AB audio amplifier manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single supply voltage ranging from 2.5 V to 5.5 V and delivers 1.4 W of output power into a 4-ohm load. The device features differential or single-ended inputs, pin-selectable turn-on time, and low quiescent current. It is housed in a compact 9-ball Wafer Level Package (WLP) suitable for surface-mount applications.

Audio Amplifiers Feature Summary

• Class AB topology for high-fidelity audio reproduction
• Supports both differential and single-ended input configurations
• Pin-selectable turn-on time to manage inrush current
• Compact 9-ball WLP footprint for space-constrained designs

Audio Amplifiers Applications

• Mobile phone speaker amplification
• Portable media player audio output stages
• Embedded electronics with limited board space
• Handheld communication devices

Audio Amplifiers Procurement Notes

Verify component authenticity through authorized distributors due to the prevalence of counterfeit audio ICs. Confirm the specific suffix matches the required package and temperature grade. Check for RoHS compliance documentation as per regulatory requirements in your target market. Ensure the supplier provides valid traceability records for quality assurance purposes.

Audio Amplifiers Selection Notes

Select this component when a mono audio solution is required with minimal external components. It is suitable for applications needing high efficiency without the complexity of Class D switching noise. Consider the WLP package size constraints and thermal dissipation capabilities relative to the enclosure design. Verify that the supply voltage range aligns with the system battery profile.

Audio Amplifiers Part Context

This part belongs to the Maxim Integrated audio amplifier family, designed for portable consumer electronics. It complements other mono and stereo amplifiers in the portfolio by offering a balance between performance and physical size. The WLP technology allows for direct integration onto mainboards without additional mounting height penalties.

Audio Amplifiers Replacement Considerations

Direct substitutes include the MAX98309EWL+T for similar mono Class AB performance. The MAX98310EWL+T offers comparable specifications within the same series. Verify pin compatibility and thermal characteristics before swapping to ensure mechanical fit.
