LM4752TS/NOPB

Audio Amplifiers Overview

The LM4752TS/NOPB is a Class-AB stereo audio power amplifier manufactured by Texas Instruments. It delivers 7 W of output power into a 4 Ohm load. The device operates within a supply voltage range of 9 V to 32 V and supports analog input signals. It features a TO-263-9 surface-mount package with a thermal pad for efficient heat dissipation. The amplifier maintains a total harmonic distortion plus noise (THD+N) of 0.08%. It functions reliably across an operating temperature range from -40°C to +85°C, with a quiescent current of 18 mA.

Audio Amplifiers Feature Summary

• Integrated thermal shutdown protection to prevent damage during overheating events
• High efficiency Class-AB operation design for balanced performance and power consumption

Audio Amplifiers Applications

• Home theater systems requiring high-power stereo audio output
• Professional PA equipment and public address amplifiers
• Car audio subwoofer and speaker driver circuits
• High-fidelity music reproduction systems

Audio Amplifiers Procurement Notes

Verify the specific suffix 'TS/NOPB' to confirm the lead-free RoHS-compliant variant in the TO-263-9 package. Ensure the ordering part number matches the exact manufacturer designation to avoid confusion with non-NOPB versions or different packaging types such as tubes versus reels. Cross-reference the datasheet revision date to confirm technical specifications remain consistent with current production standards.

Audio Amplifiers Selection Notes

Select this component when designing stereo audio stages that require significant power delivery into low-impedance loads like 4 Ohm speakers. The wide supply voltage tolerance allows flexibility in power supply design for various system architectures. Consider the thermal requirements of the TO-263-9 package and ensure adequate PCB copper area is allocated for the exposed pad to maintain safe junction temperatures under maximum load conditions.

Audio Amplifiers Part Context

This device belongs to the LM4752 family of audio power amplifiers, which are engineered for robust performance in demanding audio applications. The series is characterized by its ability to drive heavy loads while maintaining low distortion levels. The LM4752TS/NOPB specifically adapts this technology for surface-mount assembly, facilitating integration into modern printed circuit board designs where space and thermal management are critical constraints.

Audio Amplifiers Replacement Considerations

The LM4752T/NOPB serves as a through-hole alternative in a TO-220-7 package. Verify pinout compatibility and thermal interface differences before substitution. Other variants within the LM4752 series may offer similar electrical characteristics but differ in package style or mounting configuration.
