BD5632NUX-TR

Overview

The BD5632NUX-TR is a monaural Class-D speaker amplifier designed for mobile audio applications. It operates on a supply voltage range of 2.5V to 5.5V, delivering up to 2.5W output power into a 4Ω load and 1.5W into an 8Ω load at VDD=5V. The device features a fixed gain of 6dB with analog differential input and PWM digital output. Key electrical parameters include a standby current of 0.1µA, a startup time of 0.51ms, and operation within a temperature range of -40°C to 85°C.

Feature Summary

• Eliminates the need for external LC filters at the speaker output
• Supports rapid transition between standby and active modes with minimal pop noise
• Integrates protection circuits including auto-recovery short-circuit protection, thermal shutdown, and undervoltage lockout

Applications

• Mobile phone speaker amplification
• Portable electronic device audio output
• Battery-powered consumer electronics requiring high efficiency

Procurement Notes

Verify the specific suffix '-TR' confirms the taping packaging format and unit quantity of 4000 units per reel. Confirm that the base part number BD5632NUX matches the required pinout and functional specifications for your design. Ensure the standard grade classification meets your environmental and reliability requirements before finalizing procurement.

Selection Notes

Select this component when designing low-voltage audio systems that require simplified bill of materials by removing output inductors. It is suitable for applications prioritizing low standby current and fast wake-up times. Consider the 6dB fixed gain constraint and ensure the input signal amplitude aligns with the desired output power levels for the connected speaker impedance.

Part Context

This component belongs to ROHM's line of analog input Class-D amplifiers tailored for portable devices. It utilizes a digital PWM output stage to achieve high efficiency without the bulky passive components typically found in traditional Class-AB designs. The VSON008X2030 package allows for compact PCB layout in space-constrained mobile hardware.
