BD28620MUV-E2

Overview

The BD28620MUV-E2 is a Class-D stereo speaker amplifier manufactured by ROHM Semiconductor. It delivers 20 W per channel into a 6.4 Ohm load with a total harmonic distortion plus noise of 0.08%. The device operates on a single power supply ranging from 8.5 V to 24 V and features a fixed gain of 26 dB. It utilizes digital input interfaces and includes a shutdown function for power management. The component is housed in a QFN-24 package and supports an operating temperature range from -25 °C to +85 °C.

Feature Summary

• Digital input interface for direct connection to audio sources
• High efficiency Class-D topology for reduced heat generation
• Integrated shutdown control for low-power standby operation

Applications

• Ultra-thin television sets
• Space-constrained audio systems
• Energy-efficient soundbars

Procurement Notes

Verify the specific suffix against official documentation, as ordering codes may include variations for packaging or environmental compliance that do not alter electrical function. Confirm current lifecycle status, as this model is marked as Not Recommended for New Designs (NRND). Ensure compatibility with existing thermal and PCB layout constraints before procurement.

Selection Notes

Select this component when a digital input Class-D amplifier is required for applications needing 20 W output per channel. It is suitable for designs where space is limited due to its compact QFN-24 package. Consider the NRND status for long-term production viability and evaluate alternative models if new design implementation is planned.

Part Context

This part belongs to ROHM's line of digital input Class-D speaker amplifiers designed for slim consumer electronics. It shares architectural similarities with other models in the series but offers specific power and package configurations tailored for high-density board layouts.
