BU7150NUV-E2

Audio Amplifiers Overview

The BU7150NUV-E2 is a Class AB audio amplifier manufactured by ROHM Semiconductor, designed for low-voltage single-supply operation. It supports both stereo headphone and mono speaker configurations via selectable output modes. The device operates within a supply voltage range of 930 mV to 3.5 V. In single-ended stereo mode with an 8-ohm load, it delivers 60 mW per channel. In bridge-tied load (BTL) mono mode with an 8-ohm load, it provides up to 85 mW output power. The total harmonic distortion plus noise is specified at 0.2%. It features a fixed gain of 12 dB and draws approximately 1 mA of operating current. The component is housed in a compact 10-pin VSON010V3030 package.

Audio Amplifiers Feature Summary

• Supports flexible output configurations including single-ended stereo for headphones and bridge-tied load mono for speakers.
• Operates effectively at ultra-low supply voltages starting from 930 mV.
• Integrates protection mechanisms against short circuits and thermal overload.
• Includes pop-noise elimination and shutdown functionality to enhance audio quality and power efficiency.

Audio Amplifiers Applications

• Stereo headphone amplification in portable consumer electronics
• Mono speaker driving in battery-powered devices using BTL configuration
• Low-voltage audio signal processing in wearable technology

Audio Amplifiers Procurement Notes

Verify the specific suffix E2 confirms RoHS compliance status before integration. Confirm the VSON010V3030 package dimensions match your PCB footprint requirements. Ensure the design accounts for the 1 mA quiescent current draw relative to system power budgets. Validate that the 12 dB fixed gain aligns with your input signal levels. Check for any specific handling precautions associated with the exposed pad thermal design.

Audio Amplifiers Selection Notes

Select this component when designing for single-supply systems requiring operation below 1.5 V. It is suitable for applications needing either dual-channel stereo output or high-efficiency mono BTL drive. Consider the 10-pin VSON package for space-constrained layouts. Verify that the 85 mW maximum output meets the acoustic requirements of the connected transducer. Ensure the operating temperature range of -40°C to +85°C covers the intended environmental conditions.

Audio Amplifiers Part Context

This part belongs to the BU7150NUV series of audio amplifiers from ROHM Semiconductor. It is specifically engineered for mobile and portable devices where power efficiency and low voltage operation are critical. The series targets applications such as smartphones, tablets, and other handheld multimedia players. It represents a solution for integrating high-quality audio playback without complex multi-rail power supplies.

Audio Amplifiers Replacement Considerations

Check for direct pin-compatible alternatives within the ROHM portfolio if supply constraints arise. Verify that any substitute maintains the same VSON010V3030 package and electrical characteristics. Consult official substitution guides for confirmed equivalent parts. Do not assume cross-compatibility with other manufacturers' audio amplifiers without detailed parameter matching.
