LM4864MM/NOPB

Audio Amplifiers Overview

The LM4864MM/NOPB is a single-channel mono audio amplifier manufactured by Texas Instruments. It operates as a Class-AB amplifier with an analog input type. The device delivers an output power of 725 mW into an 8-ohm load. Total Harmonic Distortion plus Noise (THD+N) is specified at 0.7%. It functions within a supply voltage range of 2.7 V to 5.5 V and draws a working supply current of 3.6 mA. The component supports an operating temperature range from -40°C to +85°C and is housed in an MSOP-8 package.

Audio Amplifiers Procurement Notes

Verify the specific suffix against official documentation, as packaging variations such as tape-and-reel or cut-tape may exist for this part number. Confirm RoHS compliance status through the manufacturer's latest product data sheet. Ensure the ordering information matches the exact package style required for your PCB layout to avoid assembly discrepancies.

Audio Amplifiers Selection Notes

Select this component when a low-power, single-channel solution is required for battery-operated applications. The MSOP-8 package offers a compact footprint suitable for space-constrained designs. Consider the 2.7 V minimum supply voltage for compatibility with single-cell lithium-ion batteries. Evaluate the thermal performance requirements relative to the 725 mW output capability in the final enclosure.

Audio Amplifiers Part Context

This part belongs to the LM4864 series of audio amplifiers from Texas Instruments. The series includes variants like the LM4864M/NOPB in SOIC-8 and the LM4864MMX/NOPB in MSOP-8. These components are designed for portable audio applications requiring efficient power consumption and small form factors.

Audio Amplifiers Replacement Considerations

The LM4864MMX/NOPB serves as a verified alternative within the same family, sharing the MSOP-8 package and core functionality. Verify pinout compatibility and electrical specifications before substitution.
