LM4910MAX/NOPB

Audio Amplifiers Overview

The LM4910MAX/NOPB is a stereo Class-AB audio amplifier from the Boomer series, designed for output capacitor-less (OCL) headphone applications. It delivers 35mW of power per channel into a 32-ohm load with a total harmonic distortion plus noise (THD+N) of 0.3%. The device operates on a single supply voltage ranging from 2.2V to 5.5V and draws a typical quiescent current of 3.5mA. It features thermal shutdown protection and is housed in an 8-pin MSOP package.

Audio Amplifiers Feature Summary

• Capacitor-less output design eliminates external coupling capacitors for space savings
• Integrated thermal shutdown protects against overheating during fault conditions
• Low quiescent current consumption extends battery life in portable devices

Audio Amplifiers Applications

• Portable MP3 players and digital audio players
• Mobile phones and smartphones
• Personal media players

Audio Amplifiers Procurement Notes

Verify the specific suffix 'MAX' against official Texas Instruments documentation, as standard listings typically use 'MMX'. Confirm the package type matches your PCB footprint requirements. Ensure the operating temperature range meets your application's environmental specifications. Check for RoHS compliance status if required by your manufacturing standards.

Audio Amplifiers Selection Notes

Select this component when a compact stereo solution is needed without output capacitors. It is suitable for low-voltage battery-powered systems requiring moderate audio power. Consider the MSOP package size for tight board space constraints. Verify that the 35mW output power is sufficient for the connected headphone impedance.

Audio Amplifiers Part Context

This part belongs to the LM4910 family of audio amplifiers. It shares core functionality with variants like LM4910MMX/NOPB but may differ in packaging or regional designation. The Boomer series focuses on high-efficiency, low-power audio solutions for consumer electronics.

Audio Amplifiers Replacement Considerations

LM4910MMX/NOPB is a verified equivalent within the same family. LM4910LQX/NOPB offers a different package option. Always verify pinout compatibility and electrical parameters before substitution.
