Audio Amplifiers datasheet and documents for MAX9776ETJ+T

MAX9776ETJ+T

Audio Amplifiers Overview

The MAX9776ETJ+T is a mono Class D audio power amplifier with an integrated DirectDrive headphone amplifier, housed in a 32-pin TQFN package. It operates on a single supply voltage ranging from 2.7V to 5.5V. The device delivers up to 1.5W of output power into a 4Ω load at 5V and provides stereo headphone outputs capable of 50mW into 32Ω at 3.3V. It features ultra-low EMI through spread-spectrum modulation, I²C control for volume and configuration, and comprehensive protection including thermal and current limiting.

Audio Amplifiers Feature Summary

Ultra-low EMI achieved via active emissions limiting and spread-spectrum modulation
DirectDrive architecture eliminates the need for large DC-blocking capacitors
Flexible user-defined mixer architecture with I²C-controlled input and volume management
Integrated click-and-pop suppression for clean startup and shutdown transitions

Audio Amplifiers Applications

Cell Phones
Portable Multimedia Players
Handheld Gaming Consoles

Audio Amplifiers Procurement Notes

Verify that the suffix 'T' indicates tape-and-reel packaging rather than tube. Confirm the specific pinout matches the 32-pin TQFN variant, as other packages exist for this family. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the manufacturer's latest datasheet revision to confirm all electrical characteristics remain unchanged.

Audio Amplifiers Selection Notes

Select this part when a mono speaker amplifier combined with a stereo headphone amp is required in a compact form factor. It is suitable for designs needing high efficiency without external output filters. Consider the I²C interface if digital control over gain and mute states is necessary. Verify that the 32-pin TQFN footprint fits within the available PCB area constraints.

Audio Amplifiers Part Context

This component belongs to the MAX9775/MAX9776 series of third-generation Class D audio subsystems. While the MAX9775 offers stereo speaker amplification and 3D enhancement, the MAX9776 focuses on mono speaker output with identical headphone capabilities. Both share the same low-EMI technology and DirectDrive receiver/headphone amplifiers, differing primarily in channel configuration and package options.
