MAX9719AEUE

Audio Amplifiers Overview

The MAX9719AEUE is a Class-AB audio amplifier manufactured by Analog Devices Inc./Maxim Integrated. It features a dual-channel stereo output configuration housed in a 16-TSSOP-EP package with exposed pad. The device operates on a single supply voltage ranging from 2.7V to 5.5V and supports load impedances of 4 Ohms and 8 Ohms. It delivers up to 1.4W of output power per channel at 4 Ohms. Key electrical specifications include a differential input type, 5mA operating supply current, and an extended industrial temperature range from -40°C to +85°C.

Audio Amplifiers Feature Summary

• Supports mono or stereo operation with differential inputs for improved noise rejection
• Integrated thermal protection and pop-and-click suppression circuitry
• Operates efficiently on low-voltage single-supply systems

Audio Amplifiers Applications

• Portable multimedia devices requiring high-quality audio playback
• Personal computers and monitors with integrated speakers
• Consumer electronics utilizing small form-factor amplifiers

Audio Amplifiers Procurement Notes

Verify component authenticity through authorized distributors due to discontinued status. Confirm package marking and datasheet revision against official Analog Devices documentation. Ensure compatibility with existing PCB footprints for the 16-TSSOP-EP variant before integration into new designs.

Audio Amplifiers Selection Notes

Select this component for applications requiring balanced audio inputs and robust thermal management in compact spaces. Evaluate power requirements against the 1.4W capability at specific load impedances. Consider the exposed pad for thermal dissipation needs within the specified temperature range.
