BD5468GUL-E2

Overview

The BD5468GUL-E2 is a monaural Class-D speaker amplifier manufactured by ROHM Semiconductor, designed for analog input applications. It features an integrated Automatic Level Control (ALC) function and operates within a supply voltage range of 2.5 V to 5.5 V. The device delivers a maximum output power of 700 mW into an 8 Ω load with a total harmonic distortion plus noise of 0.2%. It utilizes a 9-pin WLCSP package measuring 1.7 × 1.7 mm with a maximum height of 0.55 mm. Key electrical parameters include a typical gain of 13 dB, a standby current of 0.01 µA, and a startup time of 1.02 ms. The component supports operation across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates digital Automatic Level Control (ALC) with fast release characteristics to manage audio levels dynamically.
• Supports differential analog input signals for improved noise immunity in portable devices.
• Achieves high efficiency up to 90% to minimize heat generation and extend battery life.
• Utilizes a compact 9-pin WLCSP footprint requiring minimal external components.

Applications

• Mobile phones and smartphones
• Laptops and notebook computers
• Home appliances equipped with voice synthesis
• Healthcare monitoring equipment

Procurement Notes

Verify the specific suffix E2 confirms RoHS compliance and lead times against current manufacturer schedules. Confirm package orientation and pin 1 identification marks match your PCB footprint design. Ensure thermal management strategies align with the WLCSP-9 package constraints during high-power operation.

Selection Notes

Select this component when differential analog input is required alongside automatic level control functionality. Compare against the BD5460 series if fixed gain without ALC is sufficient for the application. Verify that the 13 dB typical gain meets system sensitivity requirements before finalizing the design.

Part Context

This part belongs to the BD5468 series of single-channel Class-D amplifiers from ROHM. It is distinct from the BD5460 series which lacks ALC and has fixed gain. The device is optimized for low-voltage mobile applications where space and power efficiency are critical constraints.

Replacement Considerations

The BD5466GUL is a pin-compatible alternative offering higher maximum gain. The BD5460GUL serves as a substitute if ALC functionality is not needed. Verify electrical specifications and package dimensions before substituting any other models.
