BD28623MUV-DE2

Overview

The BD28623MUV-E2 is a Class-D audio amplifier manufactured by ROHM Semiconductor, designed for digital input applications. It delivers 17W per channel into an 8-ohm load with a supply voltage range of 8.5V to 24V. The device features a 26 dB gain and achieves a THD+N of 0.08%. It operates on a single power supply with a shutdown function and utilizes an I2S digital interface. The component is housed in a VQFN024V4040-24 package suitable for surface mount installation.

Feature Summary

• Supports digital input via I2S interface for direct connection to digital audio sources
• Utilizes advanced BCD process technology for high efficiency and low heat generation
• Incorporates a small back-side heat dissipation type power package for compact designs

Applications

• Ultra-slim televisions requiring space-saving solutions
• Energy-efficient audio systems
• High-quality sound reproduction in thin electronic devices

Procurement Notes

Verify the exact suffix against official documentation, as the provided model includes a 'D' which may indicate a specific variant or be a typo for the standard E2 version. Confirm RoHS compliance status and long-term availability plans directly with the manufacturer or authorized distributors before finalizing procurement decisions.

Selection Notes

Select this component for designs requiring a digital-input Class-D amplifier with high output power in a compact form factor. Ensure the system supports I2S digital signals and provides a stable 8.5V to 24V power supply. Consider the thermal requirements of the VQFN package when designing the PCB layout for optimal heat dissipation without external heatsinks.

Part Context

This part belongs to the BD2862x series of stereo speaker amplifiers from ROHM. These components are engineered for modern consumer electronics that demand both miniaturization and high-fidelity audio performance. The series leverages proprietary BCD technology to balance power output with thermal management constraints typical in slim-profile devices.

Replacement Considerations

The BD28620MUV-E2 is a related model within the same family but offers higher power output (20W+20W). Verify pin compatibility and thermal characteristics if substituting, noting that the BD28620MUV-E2 is marked as Not Recommended for New Designs.
