Audio Amplifiers datasheet and documents for LM4862M/NOPB

LM4862M/NOPB

Audio Amplifiers Overview

The LM4862M/NOPB is a mono analog input Class-AB audio power amplifier manufactured by Texas Instruments, originally designed by National Semiconductor. It delivers 675 mW of output power into an 8-ohm load. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V. It features a shutdown mode for power conservation and utilizes an 8-pin SOIC package. The operational temperature range extends from -40°C to +85°C.

Audio Amplifiers Feature Summary

Class-AB topology provides high-fidelity audio amplification with low distortion characteristics.
Integrated shutdown mode allows for significant reduction in quiescent current consumption during idle periods.
Single-supply operation simplifies circuit design by eliminating the need for dual voltage rails or output coupling capacitors.

Audio Amplifiers Applications

Portable multimedia players
Mobile telephones
Personal digital assistants

Audio Amplifiers Procurement Notes

Verify that the ordering suffix /NOPB confirms lead-free compliance and RoHS adherence as per manufacturer specifications. Confirm the package type is SOIC-8 and the thermal grade matches the intended application environment. Ensure the manufacturer designation aligns with Texas Instruments, which acquired National Semiconductor, to guarantee authenticity and correct revision levels.

Audio Amplifiers Selection Notes

Select this component when a compact, single-supply solution is required for driving small speakers in battery-operated devices. The 675 mW output capability suits applications requiring moderate volume levels without complex heat dissipation structures. Consider the shutdown feature if power efficiency is critical for extending battery life in portable electronics.

Audio Amplifiers Part Context

This part belongs to the LM4862 series of audio amplifiers. It represents a transition from discrete solutions to integrated mono amplifiers, succeeding earlier designs like the LM386 in specific low-power contexts. The device is part of the broader portfolio of audio ICs managed by Texas Instruments following the acquisition of National Semiconductor.
