MAX98357AETE+T

Audio Amplifiers Overview

The MAX98357AETE+T is a digital PCM input Class D audio amplifier manufactured by Analog Devices. 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 92% efficiency under specified conditions. It supports sample rates between 8kHz and 96kHz with 16/24/32-bit data resolution. The component utilizes a 16-pin TQFN package (3mm x 3mm) and functions within an operating temperature range of -40°C to +85°C.

Audio Amplifiers Feature Summary

• Eliminates the need for external master clock signals through automatic recognition of PCM and TDM clocking schemes.
• Employs filterless spread-spectrum modulation with edge-rate limiting to significantly reduce electromagnetic interference.
• Integrates sophisticated click-and-pop suppression circuitry alongside robust short-circuit and thermal protection mechanisms.

Audio Amplifiers Applications

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

Audio Amplifiers Procurement Notes

Verify that the specific suffix 'ETE' corresponds to the 16-pin TQFN package variant rather than the WLP option. Confirm RoHS compliance status as indicated in official documentation. Ensure compatibility with the required I2S or TDM interface protocols before integration. Cross-reference the manufacturer's latest datasheet revision to validate all electrical characteristics against the intended application environment.

Audio Amplifiers Selection Notes

Select this component when a compact, low-cost solution is required for digital audio amplification without external filtering. It is suitable for applications demanding high efficiency and minimal board space. Consider the fixed gain options available via pin configuration. Evaluate the thermal dissipation requirements associated with the TQFN package layout for optimal performance.

Audio Amplifiers Part Context

This part belongs to the MAX98357 family, which includes variants like the MAX98357B supporting left-justified data formats. The MAX98357A specifically handles standard I2S data inputs. Both versions share identical physical dimensions and electrical capabilities, differing primarily in digital audio interface timing configurations. The ETE designation identifies the surface-mount TQFN package version.

Audio Amplifiers Replacement Considerations

The MAX98357B serves as a functional alternative for designs requiring left-justified digital audio interfaces instead of I2S. Other packages such as the WLP variant offer smaller footprints but require different PCB routing strategies. Verify pinout compatibility and software configuration differences when substituting related models.
