LM4910MM/NOPB

Audio Amplifiers Overview

The LM4910MM/NOPB is a stereo Class-AB audio amplifier manufactured by Texas Instruments, designed specifically for driving headphone loads. It delivers 35mW of output power per channel into a 32-ohm impedance. The device operates on a single supply voltage ranging from 2.2V to 5.5V and draws a typical quiescent current of 3.5mA. Total Harmonic Distortion plus Noise (THD+N) is specified at 0.3%. It utilizes an 8-pin VSSOP surface-mount package and supports an operating temperature range from -40°C to +85°C.

Audio Amplifiers Feature Summary

• Capacitor-less output architecture eliminates the need for external coupling capacitors, reducing component count and board space.
• Low quiescent current consumption extends battery life in portable electronic devices.
• Integrated thermal protection safeguards the device during high-power operation or overheating conditions.

Audio Amplifiers Applications

• Portable MP3 players
• Mobile phones
• Personal digital assistants

Audio Amplifiers Procurement Notes

Verify the specific suffix MM/NOPB against the manufacturer's latest datasheet to confirm the 8-VSSOP package and lead-free status. Ensure the ordering quantity aligns with standard factory packaging configurations. Cross-reference the part number with authorized distributors to confirm current availability and authenticity before finalizing procurement.

Audio Amplifiers Selection Notes

Select this component when designing low-power stereo audio systems requiring capacitor-less outputs. It is suitable for applications powered by single-cell lithium-ion batteries or dual AA/AAA battery packs. Consider the 8-VSSOP package constraints for PCB layout and thermal management requirements in compact enclosures.

Audio Amplifiers Part Context

This part belongs to the LM4910 family of Boomer® audio amplifiers. It shares functional similarities with other variants like the LM4910LQ/NOPB but differs in physical packaging. The MM suffix denotes the VSSOP package type, distinguishing it from WQFN or other form factors within the same electrical specification set.

Audio Amplifiers Replacement Considerations

LM4910LQ/NOPB offers identical electrical performance in an 8-WQFN package. LM4910MMX/NOPB provides the same functionality in an 8-VSSOP package with reel packaging. Verify pinout compatibility and thermal characteristics when substituting between package types.
