MAX98355BEWL+T

Audio Amplifiers Overview

The MAX98355BEWL+T is a single-channel mono Class D audio power amplifier manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 2.5 V to 5.5 V and delivers an output power of 3.2 W into an 8-ohm load. The device features a total harmonic distortion plus noise (THD+N) of 0.013% and draws a quiescent current of 2.2 mA. It is housed in a compact 9-WLP surface-mount package and supports an operating temperature range from -40°C to +85°C.

Audio Amplifiers Feature Summary

• Integrates PCM digital input interface for direct connection to audio sources
• Includes built-in pop-and-click suppression circuitry to minimize audible transients during power-up and power-down sequences
• Provides comprehensive protection mechanisms including thermal shutdown and short-circuit protection

Audio Amplifiers Applications

• Mobile phone speaker systems
• Tablet computer audio outputs
• Portable media players

Audio Amplifiers Procurement Notes

Verify component authenticity through authorized distribution channels due to limited availability status. Confirm that the specific suffix matches the required reel or cut tape packaging format. Ensure compliance with RoHS3 standards and check for any regional sales restrictions before finalizing procurement orders.

Audio Amplifiers Selection Notes

Select this component when a digital PCM input interface is required rather than analog inputs. Evaluate the 9-WLP package constraints against available PCB real estate. Consider the 3.2 W output capability relative to the target speaker impedance and desired volume levels within the specified voltage range.

Audio Amplifiers Part Context

This part belongs to the MAX98355B series of digital-input Class D amplifiers designed for mobile applications. It represents a solution for simplifying system design by eliminating external components typically needed for analog amplification stages while maintaining high audio fidelity.
