LM4990MM/NOPB

Audio Amplifiers Overview

The LM4990MM/NOPB is a single-channel, analog input Class-AB audio power amplifier manufactured by Texas Instruments. It delivers 2W of output power into an 8-ohm load and operates within a supply voltage range of 2.6V to 5.5V. The device features a total harmonic distortion plus noise (THD+N) of 0.2% at rated output. It is housed in a VSSOP-8 surface-mount package and supports an operating temperature range from -40°C to +85°C.

Audio Amplifiers Feature Summary

• Delivers high-fidelity audio amplification with low distortion characteristics for clear sound reproduction.
• Operates efficiently on low-voltage single-supply configurations suitable for portable electronics.
• Integrates protection mechanisms to ensure reliable performance under varying thermal conditions.

Audio Amplifiers Applications

• Portable media players
• Mobile phones
• Personal digital assistants

Audio Amplifiers Procurement Notes

Verify the specific suffix NOPB indicates lead-free compliance when sourcing. Confirm the VSSOP-8 package dimensions match your PCB footprint requirements. Ensure the design accommodates the specified thermal dissipation limits for continuous operation at maximum power levels.

Audio Amplifiers Selection Notes

Select this component for designs requiring a balance between output power and supply voltage constraints. It is appropriate for applications where space is limited due to its compact VSSOP-8 form factor. Consider the 0.2% THD specification against the acoustic requirements of the target speaker system.
