MAX9738EWP+TG45

Audio Amplifiers Overview

The MAX9738EWP+TG45 is a single-channel Class G audio power amplifier manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 2.7V to 5.5V and delivers high efficiency suitable for portable applications. The device utilizes a 20-WLP (Wafer Level Package) or WFBGA/WLBGA form factor for surface mount installation. Key electrical parameters include an operating temperature range from -40°C to +85°C (TA). The component integrates features such as pop-and-click suppression, differential input capability, and a shutdown mode to optimize performance in battery-powered systems.

Audio Amplifiers Feature Summary

• Class G architecture provides enhanced power efficiency compared to traditional linear amplifiers.
• Integrated pop-and-click suppression circuitry eliminates audible noise during power transitions.
• Supports differential input configurations to improve noise immunity in signal paths.
• Includes a dedicated shutdown function to minimize current consumption when inactive.

Audio Amplifiers Applications

• Portable audio devices requiring efficient mono amplification
• Mobile phones and smartphones with limited power budgets
• Personal media players and digital audio assistants

Audio Amplifiers Procurement Notes

Verify the specific suffix TG45 against the manufacturer's official datasheet to confirm RoHS compliance and lead-free status. Confirm package type alignment between 20-WLP and WFBGA designations if mechanical constraints are critical. Check current availability status as distribution channels may list this part as obsolete or discontinued. Ensure ordering documentation matches the exact Maxim Integrated part number to avoid substitution errors.

Audio Amplifiers Selection Notes

Select this component for designs requiring a single-channel output with moderate power delivery under low-voltage conditions. The Class G topology is appropriate where efficiency is prioritized over maximum output swing. Verify that the system power supply remains within the 2.7V to 5.5V operational window. Consider the thermal characteristics of the 20-WLP package for PCB layout planning in compact enclosures.

Audio Amplifiers Part Context

This part belongs to the MAX9738 family of audio amplifiers designed by Maxim Integrated, now part of Analog Devices. The series focuses on delivering high-quality audio performance in space-constrained mobile electronics. The EWP variant specifically denotes the wafer-level packaging option, distinguishing it from other pinout or package configurations within the same functional family.
