BD5424EFS-E2

Overview

The BD5424EFS-E2 is a Class-D audio amplifier manufactured by ROHM Semiconductor, designed for speaker amplification applications. It features a bridge output configuration with two channels and delivers an output power of 20 W per channel. The device operates within a supply voltage range of 10 V to 18 V and maintains a total harmonic distortion plus noise (THD+N) of 0.1%. Key electrical parameters include a gain of 28 dB, a single input type, and a quiescent current of 30 mA. It supports a shutdown function and functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

Class-D topology for efficient audio amplification
Bridge output configuration for dual-channel operation
Integrated shutdown control for power management

Applications

Speaker amplification systems
Audio IC circuits

Procurement Notes

Verify the specific ordering suffix E-2 against the manufacturer's datasheet to confirm package and tape specifications. Confirm RoHS compliance status directly with the supplier documentation. Ensure the HTSSOP-44 package dimensions match your PCB footprint requirements before finalizing procurement decisions.

Selection Notes

Select this component when a high-efficiency Class-D amplifier is required for driving speakers in automotive or industrial environments. The 10 V to 18 V supply range suits standard vehicle battery systems. Verify that the 20 W output power meets the load impedance requirements and that the thermal performance in the HTSSOP-44 package is adequate for the intended enclosure design.
