LM48861TM/NOPB

Audio Amplifiers Overview

The LM48861TM/NOPB is a stereo Class-AB audio amplifier designed for low-voltage mobile applications. It delivers 24 mW of continuous output power into a 32 Ohm load with less than 0.04% total harmonic distortion plus noise at a 2.8 V supply voltage. The device operates on a single power supply ranging from 1.2 V to 2.8 V and draws only 2 mA of quiescent current. It features integrated short-circuit protection, thermal shutdown, and pop-and-click suppression circuitry to minimize audible transients during power-up and power-down cycles.

Audio Amplifiers Feature Summary

• Stereo Class-AB architecture optimized for portable devices
• Integrated pop-and-click suppression for transient-free operation
• Built-in short-circuit and thermal protection mechanisms

Audio Amplifiers Applications

• Mobile phone speaker amplification
• Personal digital assistant (PDA) audio output
• Portable media player headphone drivers

Audio Amplifiers Procurement Notes

Verify the suffix TM indicates the specific tape and reel packaging configuration required for surface-mount assembly processes. Confirm that the NOPB designation ensures compliance with current environmental standards. Cross-reference the manufacturer's latest datasheet revision to ensure all electrical characteristics match the design requirements before finalizing procurement orders.

Audio Amplifiers Selection Notes

Select this component when designing circuits requiring stereo amplification within strict low-voltage constraints. It is suitable for systems powered by single-cell lithium-ion batteries or similar low-voltage sources. Consider its small uSMD package footprint if board space is limited. Ensure the application does not require high-power output exceeding 24 mW per channel.

Audio Amplifiers Part Context

This part belongs to Texas Instruments' portfolio of low-power audio solutions. It complements other members of the LM4886x series, which share similar functional blocks but vary in output power and packaging options. The device addresses the market demand for high-fidelity audio in compact consumer electronics where power efficiency is critical.

Audio Amplifiers Replacement Considerations

LM48860TL/NOPB offers similar stereo functionality with slightly different power specifications.
