MAX9718AETB

Audio Amplifiers Overview

The MAX9718AETB is a 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 continuous output power into a 4Ω load. The device features differential inputs, pop-and-click suppression, and thermal protection. It is housed in a compact 16-TQFN package with an exposed pad for enhanced thermal dissipation.

Audio Amplifiers Feature Summary

• Delivers high-efficiency stereo audio amplification with minimal external components
• Integrates internal pop-and-click suppression for silent startup and shutdown
• Supports differential input configurations to improve noise immunity

Audio Amplifiers Applications

• Portable multimedia devices requiring low-voltage operation
• Handheld gaming consoles and personal media players
• Bluetooth speakers and wireless audio transmitters

Audio Amplifiers Procurement Notes

Verify the exact suffix against the manufacturer's current datasheet to ensure pinout and thermal pad compatibility. Confirm RoHS compliance status as manufacturing processes may evolve. Cross-reference the specific revision level with your design requirements to avoid integration issues with existing PCB layouts.

Audio Amplifiers Selection Notes

Select this component when designing battery-powered systems that require high fidelity without complex biasing networks. The differential input capability simplifies layout compared to single-ended designs. Ensure adequate thermal relief on the PCB due to the exposed pad requirement for optimal heat dissipation during high-power operation.

Audio Amplifiers Part Context

This part belongs to the MAX9718/MAX9719 family of ultra-low-voltage audio amplifiers. These devices are designed specifically for portable applications where power efficiency and sound quality are critical. The family shares similar architectural features but varies in packaging and channel configuration to suit different form factors.

Audio Amplifiers Replacement Considerations

Direct substitutes include the MAX9719AETE+ series. Verify that the replacement maintains the same TQFN footprint and thermal characteristics. Check if the alternative offers identical pop-and-click performance and differential input support.
