Audio Amplifiers datasheet and documents for MAX9777ETI+T

MAX9777ETI+T

Audio Amplifiers Overview

The MAX9777ETI+T is a stereo audio amplifier in the MAX9777 series, manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single supply voltage ranging from 4.5 V to 5.5 V and utilizes a 28-TQFN (5x5 mm) surface-mount package. The device delivers up to 2.6 W per channel into a 4-ohm load or 200 mW per channel into a 16-ohm load. It features Class-AB topology with integrated I2C control, input multiplexing, depopulation, mute, shutdown, and thermal protection functions.

Audio Amplifiers Feature Summary

Integrated I2C interface for digital control of gain, mute, and shutdown states
Built-in input multiplexer allowing selection between multiple audio sources
On-chip depopulation circuitry to eliminate speaker popping during power transitions
Thermal protection mechanism to safeguard the device under high-load conditions

Audio Amplifiers Applications

Portable multimedia devices requiring stereo audio output
Embedded systems utilizing I2C-controlled audio routing
Battery-powered consumer electronics needing efficient Class-AB amplification

Audio Amplifiers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for obsolescence notices, as this part may be discontinued. Ensure packaging specifications match design requirements before procurement.

Audio Amplifiers Selection Notes

Select this component when I2C programmability and input switching are required alongside moderate power output. Evaluate thermal performance for 4-ohm loads and ensure supply voltage remains within the 4.5 V to 5.5 V range. Consider package size constraints due to the 28-TQFN footprint.

Audio Amplifiers Part Context

Part of the MAX9777 family of stereo audio amplifiers designed for portable applications. Offers integrated control features reducing external component count compared to basic amplifier designs.

Audio Amplifiers Replacement Considerations

MAX9777ETI+T is available in tape-and-reel packaging as an alternative to the tube-packaged MAX9777ETI+. Verify pin compatibility and thermal characteristics when substituting.
