MAX9719DETE+T

Audio Amplifiers Overview

The MAX9719DETE+T is a dual-channel, low-cost audio power amplifier designed for portable stereo systems. It operates from a single 2.7V to 5.5V supply and delivers 1.4W continuous average power per channel into a 4Ω load with less than 1% THD+N at +5V. The device features a bridge-tied load architecture, differential inputs for improved noise rejection, and internally fixed gain options. It includes a low-power shutdown mode reducing current to under 100nA and integrated click-and-pop suppression circuitry.

Audio Amplifiers Feature Summary

• Dual-channel stereo amplification with bridge-tied load output configuration
• Differential input structure providing high common-mode noise rejection
• Integrated click-and-pop suppression for quiet startup and shutdown transitions
• Low-power shutdown mode significantly reduces quiescent current consumption

Audio Amplifiers Applications

• Mobile phones
• Personal digital assistants (PDAs)
• Portable electronic devices

Audio Amplifiers Procurement Notes

Verify the specific suffix DETE corresponds to the 16-pin TQFN package variant when sourcing. Confirm RoHS compliance status indicated by the '+' designation in the ordering information. Ensure the selected component matches the required thermal performance characteristics for the intended enclosure design.

Audio Amplifiers Selection Notes

Select this model for applications requiring stereo output from a single IC. Choose based on the need for fixed internal gain versus adjustable external gain variants. Consider the 16-pin TQFN package constraints regarding thermal dissipation and board space availability compared to other available package options.

Audio Amplifiers Part Context

This component belongs to the MAX9718/MAX9719 family of mono and stereo audio amplifiers. While the MAX9718 provides single-channel output, the MAX9719 offers dual-channel capability. Both share similar electrical characteristics, packaging options, and interface protocols within the same product line.

Audio Amplifiers Replacement Considerations

The datasheet notes pin compatibility with the LM4895 for the MAX9718 mono variant. No direct substitute part numbers are explicitly listed for the MAX9719 dual-channel version in the provided documentation.
