MAX9778ETI+T

Audio Amplifiers Overview

The MAX9778ETI+T is a Class AB stereo audio amplifier manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single supply voltage ranging from 4.5V to 5.5V and is housed in a 28-TQFN (5x5mm) surface-mount package with an exposed pad. The device delivers up to 2.6W per channel into a 4-ohm load, or 200mW per channel into a 16-ohm load. It integrates features including depopulation, input multiplexing, mute, shutdown, and thermal protection, functioning within a temperature range of -40°C to +85°C.

Audio Amplifiers Feature Summary

Integrates input multiplexer for flexible signal routing
Includes thermal protection circuitry for operational safety
Supports direct drive for stereo headphones

Audio Amplifiers Applications

Portable multimedia devices requiring high-fidelity audio output
Stereo headphone amplification circuits
Battery-powered consumer electronics

Audio Amplifiers Procurement Notes

Verify component authenticity through authorized distributors or the manufacturer directly. Confirm RoHS compliance status and check for obsolescence notices, as this part may be discontinued. Ensure the specific suffix matches the required tape-and-reel packaging format for automated assembly processes.

Audio Amplifiers Selection Notes

Select this component when a single-supply Class AB solution is required for driving low-impedance loads like 4-ohm speakers. Consider its integrated protection features and multiplexer capabilities if board space is limited. Evaluate power dissipation requirements against the thermal performance of the TQFN package.

Audio Amplifiers Part Context

This component belongs to the Maxim Integrated audio amplifier family, designed for portable applications. It represents a transition point where Class AB quality is combined with modern surface-mount packaging. The ETI+T designation indicates the specific lead-free, tape-and-reel variant of the MAX9778 series.
