Overview
The BD5426MUV-E2 is a two-channel stereo Class-D audio amplifier manufactured by ROHM Semiconductor. It operates on a single power supply ranging from 10 V to 16.5 V and delivers up to 10 W per channel into an 8-ohm load, or 4.8 W into a 16-ohm load. The device features a fixed gain of 28 dB with a total harmonic distortion plus noise of 0.1%. It utilizes a QFN-48 package (VQFN048V7070) and supports operation within a temperature range of -40°C to +85°C.
Feature Summary
- Integrates differential output architecture for stereo audio amplification
- Includes protection mechanisms against short circuits and thermal overload
- Supports pop-suppression and mute functions for signal control
Applications
- Portable audio devices requiring high efficiency
- Small panel speaker systems
- Consumer electronics with analog input interfaces
Procurement Notes
Verify component authenticity through authorized channels as the part is marked NRND. Confirm package integrity due to moisture sensitivity classification. Ensure design compatibility with existing single-supply voltage rails between 10 V and 16.5 V. Check for lead-free compliance status if required by specific regional regulations.
Selection Notes
Select this component for designs requiring a compact stereo solution with minimal external components. The fixed 28 dB gain simplifies circuit design compared to adjustable gain variants. Consider the QFN-48 footprint constraints during PCB layout. Evaluate thermal management requirements given the power dissipation characteristics in enclosed spaces.
Part Context
This model belongs to the BD54 series of audio amplifiers from ROHM Semiconductor. It shares functional similarities with other Class-D amplifiers in the lineup but differs in package type and specific output power ratings. The E2 suffix typically indicates environmental compliance attributes consistent with manufacturer standards.
Replacement Considerations
No officially confirmed substitute part numbers are documented in the provided source material.
