BD5467GUL-E2

Overview

The BD5467GUL-E2 is a monaural Class-D speaker amplifier manufactured by ROHM Semiconductor. It features an analog input interface and operates within a supply voltage range of 2.5 V to 5.5 V. The device delivers an output power of 700 mW with a total harmonic distortion plus noise (THD+N) of 0.2%. It incorporates a fixed gain of 13 dB and draws a typical operating supply current of 3 mA. The component supports a shutdown function for power management and is housed in a compact WLCSP-9 package, suitable for surface mount installation.

Feature Summary

• Class-D topology provides high efficiency and low power consumption for battery-driven applications.
• Integrated automatic recovery short-circuit protection and thermal shutdown mechanisms enhance reliability.
• Built-in pop-noise reduction circuit minimizes audible artifacts during startup and standby transitions.

Applications

• Mobile phones
• Portable electronic devices
• Battery-powered audio equipment

Procurement Notes

Verify the specific suffix E2 against the manufacturer's latest datasheet to confirm compliance with current environmental standards and material declarations. Ensure the ordering quantity aligns with the factory packaging requirements specified in the official documentation. Cross-reference the part number with authorized distributor catalogs to confirm availability and lead times prior to finalizing procurement plans.

Selection Notes

Select this component when a single-channel audio solution with analog input is required for space-constrained portable designs. The fixed 13 dB gain simplifies external circuitry compared to variable gain alternatives. Consider the WLCSP-9 package dimensions for PCB layout constraints and verify that the 700 mW output capability meets the specific speaker impedance and volume requirements of the target application.

Part Context

This part belongs to the BD546xGUL series of wafer-level CSP packaged low-voltage monaural Class-D speaker amplifiers developed by ROHM Semiconductor. The series targets mobile phone and portable electric device markets. Unlike variable gain models such as the BD27400GUL, this specific variant utilizes a fixed gain architecture with integrated Automatic Level Control (ALC) capabilities.
