Overview
The BD5423MUV-E2 is a Class-D audio amplifier manufactured by ROHM Semiconductor, designed for analog input applications. It features a dual-channel stereo configuration housed in a QFN-48 surface-mount package. The device operates within a supply voltage range of 10 V to 16.5 V and delivers an output power of 4.8 W into a 16 Ohm load. Key electrical specifications include a gain of 28 dB, a THD+N of 0.1%, and a quiescent current of 25 mA. It supports single-ended input and functions reliably across an operating temperature range from -40°C to +85°C.
Feature Summary
- Class-D topology for efficient audio amplification
- Dual-channel stereo output capability
- Integrated shutdown functionality for power management
Applications
- Analog input speaker amplification systems
- Portable audio devices requiring low power consumption
- Embedded audio circuits in consumer electronics
Procurement Notes
Verify the component status before integration, as the BD5423MUV-E2 is classified as NRND (Not Recommended for New Designs). Confirm that existing inventory or last-time buy options meet project requirements. Ensure compatibility with the QFN-48 footprint and validate thermal performance within the specified -40°C to +85°C operating range during final design review.
Selection Notes
Select this component when a compact, low-power Class-D solution for analog inputs is required. The 4.8 W output at 16 Ohms suits smaller speakers. Consider the NRND status for long-term production viability. The QFN-48 package offers space efficiency but requires appropriate PCB layout for thermal dissipation and signal integrity given the 25 mA operating current.
Part Context
This part belongs to the BD54 series of audio ICs from ROHM Semiconductor. It is categorized under Audio Amplifiers and specifically falls within the Audio ICs subcategory. The manufacturer identifies it as a 2-Channel Stereo Speaker Amplifier type, distinct from other ROHM products like the BD9134MUV-E2 switching regulator or BD28623MUV-E2 digital input amplifier.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the NRND status, alternative components should be evaluated based on matching pinout, package type (QFN-48), and electrical specifications such as 10-16.5 V supply range and 4.8 W output power.
