LM4862MX

Audio Amplifiers Overview

The LM4862MX is a mono audio power amplifier manufactured by Texas Instruments, formerly National Semiconductor. It delivers 675 mW of output power into an 8-ohm load with a supply voltage range of 2.7 V to 5.5 V. The device operates in Class-AB topology and features a shutdown mode for power conservation. It utilizes a single analog input and has a typical quiescent current of 1 mA. The unit is housed in an 8-pin SOIC package and supports surface-mount installation.

Audio Amplifiers Feature Summary

• Integrated shutdown mode for low-power standby operation
• Class-AB amplification for high-fidelity audio reproduction
• Single-channel mono configuration with analog input

Audio Amplifiers Applications

• Portable media players
• Mobile phones
• Personal digital assistants

Audio Amplifiers Procurement Notes

Verify the manufacturer designation as Texas Instruments, which acquired National Semiconductor. Confirm the suffix MX indicates the SOIC-8 package variant. Ensure the NOPB designation is present if lead-free compliance is required. Cross-reference the datasheet revision date to ensure compatibility with current design specifications.

Audio Amplifiers Selection Notes

Select this component for applications requiring a compact mono amplifier with integrated power management. The low quiescent current makes it suitable for battery-operated devices. Verify that the 675 mW output power meets the specific acoustic requirements of the target application before finalizing the design.

Audio Amplifiers Part Context

This part belongs to the LM486x series of audio amplifiers designed for portable electronics. It shares functional similarities with the LM4861 but offers lower power output. The series is characterized by its ability to operate from a single supply voltage while maintaining low distortion levels.
