BM28723AMUV-E2

Audio Amplifiers Overview

The BM28723AMUV-E2 is a two-channel Class-D digital speaker amplifier manufactured by ROHM Semiconductor. It integrates a digital signal processor and operates with an I2S digital input interface. The device delivers 17 watts of output power per channel into an 8-ohm load, achieving a total harmonic distortion plus noise of 0.08 percent. It functions within a supply voltage range of 10 volts to 24 volts and maintains a gain of 26 decibels. The component operates at a quiescent current of 45 mA and supports temperatures from -25°C to +85°C. It is housed in a VQFN032V5050-32 surface-mount package.

Audio Amplifiers Feature Summary

• Integrates a digital signal processor for audio processing alongside the amplifier stage
• Accepts direct digital audio inputs via the I2S interface
• Provides high-efficiency Class-D amplification with low distortion characteristics

Audio Amplifiers Applications

• Digital audio systems requiring integrated DSP and amplification
• Consumer electronics utilizing I2S digital audio sources
• Portable or fixed audio devices operating on single-supply voltages

Audio Amplifiers Procurement Notes

Verify the specific suffix E2 against the manufacturer's latest documentation to confirm compliance status and pinout compatibility. Confirm that the VQFN032V5050-32 package dimensions align with the target PCB footprint. Ensure the design supports the required 10V to 24V supply range and I2S digital interface timing specifications before finalizing procurement.

Audio Amplifiers Selection Notes

Select this component when a combined DSP and amplifier solution is required to reduce system complexity. It is suitable for designs where digital audio interfaces are preferred over analog inputs. Consider the thermal performance of the VQFN package and the 17W output capability relative to the connected speaker impedance. Verify that the 26dB gain setting meets the system's signal chain requirements.

Audio Amplifiers Part Context

This part belongs to ROHM's family of digital speaker amplifiers designed for modern audio applications. It combines power amplification with digital signal processing capabilities in a compact form factor. The integration of DSP allows for advanced audio tuning directly within the amplifier IC, reducing the need for external processing components.

Audio Amplifiers Replacement Considerations

The BD28623MUV-E2 is a related Class-D amplifier from ROHM but lacks the integrated DSP and uses a different 24-pin package. Cross-referencing requires verifying interface compatibility and physical footprint differences.
