MAX9719DETE

Audio Amplifiers Overview

The MAX9719DETE+ is a dual-channel Class AB audio power amplifier manufactured by Analog Devices Inc. (Maxim Integrated). It operates on a single supply voltage ranging from 2.7V to 5.5V and delivers up to 1.4W of output power per channel into a 4-ohm load. The device is housed in a compact 16-TQFN package measuring 4x4 mm with an exposed pad for thermal management. It supports stereo operation and includes integrated features such as pop-and-click suppression, differential input capability, shutdown control, and thermal protection.

Audio Amplifiers Feature Summary

• Integrated pop-and-click suppression circuitry minimizes audible noise during power-up and power-down sequences.
• Supports differential input configurations to improve noise immunity in signal paths.
• Includes built-in thermal protection to safeguard the device under high-temperature operating conditions.
• Features a dedicated shutdown pin for efficient power management in portable applications.

Audio Amplifiers Applications

• Portable multimedia devices requiring high-quality stereo audio playback
• Mobile phones and smartphones with limited power budgets
• Personal digital assistants and handheld gaming consoles
• MP3 players and portable media receivers

Audio Amplifiers Procurement Notes

Verify the exact suffix designation, as the provided model lacks the standard '+' or 'T' indicators found in official datasheets. Confirm RoHS compliance status and check for obsolescence notices, as this component may be discontinued. Ensure the supplier provides valid traceability documentation matching the manufacturer's part numbering system before finalizing procurement.

Audio Amplifiers Selection Notes

Select this component when designing stereo audio systems that require Class AB performance within a small footprint. It is suitable for battery-powered devices where efficiency and audio fidelity are balanced. Consider the 16-TQFN package constraints for PCB layout and thermal dissipation requirements compared to larger packages like WLP or SOIC alternatives.

Audio Amplifiers Part Context

This component belongs to the Maxim Integrated MAX9718/MAX9719 family of audio amplifiers. These devices are designed for low-voltage, single-supply applications. The MAX9719 variant specifically offers dual-channel stereo output, distinguishing it from the mono MAX9718. The family is characterized by its ability to deliver significant power from low voltage supplies using advanced Class AB topology.

Audio Amplifiers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with existing designs by comparing pinouts, electrical characteristics, and thermal performance against potential alternatives from the same manufacturer or other vendors.
