BM28723MUV-E2

Audio Amplifiers Overview

The BM28723MUV-E2 is a Class-D digital speaker amplifier manufactured by ROHM Semiconductor. It delivers 17 W per channel into an 8-ohm load with a total harmonic distortion plus noise of 0.08%. The device operates on a single power supply ranging from 10 V to 24 V and features I2S digital input. It utilizes a VQFN032V5050-32 package, supports a gain of 26 dB, and includes a shutdown function. The component functions within a temperature range of -25°C to +85°C.

Audio Amplifiers Feature Summary

• Integrates a digital signal processor for audio processing alongside the Class-D amplifier stage.
• Accepts direct digital audio inputs via the I2S interface without requiring external DACs.
• Employs a compact surface-mount package designed for space-constrained applications.

Audio Amplifiers Applications

• Audio systems in ultra-thin televisions
• Compact home theater speakers
• Portable digital audio devices

Audio Amplifiers Procurement Notes

Verify the specific suffix E2 against the manufacturer's current datasheet to confirm compliance with RoHS directives and material declarations. Confirm that the VQFN032V5050-32 package dimensions match your PCB footprint requirements. Ensure the I2S interface timing aligns with your host processor specifications before finalizing procurement.

Audio Amplifiers Selection Notes

Select this component when a fully digital audio path is required to minimize external components. It is suitable for designs needing high output power relative to its small physical size. Consider the thermal performance of the VQFN package if operating near maximum voltage limits. Verify that the system architecture supports the necessary I2S clocking and data formats.

Audio Amplifiers Part Context

This part belongs to ROHM's series of digital speaker amplifiers designed for modern consumer electronics. It represents a shift toward integrating DSP capabilities directly within the amplifier IC to reduce board space. The product line targets the demand for high-fidelity audio in increasingly slim device form factors.

Audio Amplifiers Replacement Considerations

The BD28623MUV-E2 is a related stereo Class-D amplifier but lacks the integrated DSP and uses a different VQFN24 package. Cross-referencing pinouts and thermal characteristics is essential when considering alternative models from the same manufacturer family.
