MAX98357AETE+

Audio Amplifiers Overview

The MAX98357AETE+T is a digital PCM input Class D audio amplifier manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single supply voltage ranging from 2.5V to 5.5V and delivers up to 3.2W of output power into a 4Ω load at 5V. The device features a quiescent current of 2.4mA and achieves an efficiency of 92% with an 8Ω load at 1W output. It utilizes a 16-pin TQFN (3mm x 3mm) package and supports sample rates between 8kHz and 96kHz.

Audio Amplifiers Feature Summary

• Eliminates the need for an external master clock signal, simplifying system design and reducing electromagnetic interference.
• Employs filterless spread-spectrum modulation with edge-rate control to minimize radiated emissions without requiring output filtering components.
• Integrates sophisticated click-and-pop suppression circuitry to reduce audible transients during startup and shutdown sequences.
• Provides robust protection mechanisms including thermal overload and short-circuit protection for reliable operation.

Audio Amplifiers Applications

• Smart speakers
• Notebook computers
• IoT devices
• Gaming devices

Audio Amplifiers Procurement Notes

Verify that the component matches the specific MAX98357AETE+T designation, as the base part number covers multiple package options. Confirm the manufacturer is Analog Devices or Maxim Integrated. Ensure the datasheet revision aligns with the required specifications. Check for RoHS compliance documentation if environmental standards are mandatory for the project.

Audio Amplifiers Selection Notes

Select this component when a compact solution is required that integrates both digital-to-analog conversion and amplification. It is suitable for designs where minimizing board space and component count is critical. The absence of an external MCLK requirement makes it ideal for interfaces with limited clock outputs. Consider the TQFN package for its thermal dissipation capabilities in dense layouts.

Audio Amplifiers Part Context

This component belongs to the MAX98357 family, which includes variants like the MAX98357B supporting left-justified data formats. The family is designed to provide Class AB audio performance with Class D efficiency. Other packages available include a 9-pin WLP for ultra-small form factors. The device is widely used in portable electronics due to its low power consumption and high integration level.
