BD5638NUX-TR

Overview

The BD5638NUX-TR is a mono Class-D audio power amplifier manufactured by ROHM Semiconductor. It delivers 2.5W of output power into a 4-ohm load. The device operates within a supply voltage range of 2.7V to 5.5V and draws an operating supply current of 2.7mA. It features analog input and utilizes an 8-pin VSON (3x2mm) package with an exposed pad for thermal management.

Feature Summary

Class-D topology for high efficiency
Mono channel configuration
Analog signal input interface

Applications

Portable audio devices
Small form-factor speakers
Battery-powered consumer electronics

Procurement Notes

Verify the specific suffix and tape/reel specifications against the official datasheet before procurement. Ensure compatibility with the target PCB footprint, specifically the 8-VSON (3x2) package dimensions. Confirm that the supply voltage requirements align with the system design constraints.

Selection Notes

Select this component when a single-channel, high-efficiency amplification solution is required for low-voltage applications. The 2.5W output capability at 4 ohms makes it suitable for compact speaker systems. Consider the 2.7mA quiescent current for battery life optimization in portable designs.

Part Context

This part belongs to ROHM's audio amplifier product line, designed for mobile and portable electronics. The BD5638NUX-TR variant specifically offers a balance of power output and size efficiency, utilizing the VSON package to minimize board space while maintaining adequate thermal performance through the exposed pad.

Replacement Considerations

Consult official substitution guides for direct pin-compatible alternatives. Verify electrical parameters such as output power and supply voltage ranges match the original design requirements before replacing.
