LM4907LQX

Audio Amplifiers Overview

The LM4907LQX is a Class AB mono audio power amplifier manufactured by Texas Instruments. It delivers 1.07 W of output power into an 8 Ω load. The device operates from a single supply voltage ranging from 2.5 V to 5.5 V. It utilizes an 8-WQFN package with an exposed pad, measuring 2 mm by 2 mm. Key electrical characteristics include a quiescent current of 6 mA and a shutdown current of less than 1 µA. The amplifier features integrated pop-and-click suppression circuitry to minimize audible transients during power-up and power-down sequences.

Audio Amplifiers Feature Summary

• Integrated pop-and-click suppression circuitry eliminates audible transients during power transitions.
• Class AB topology provides high-fidelity audio amplification with low distortion.
• Shutdown mode significantly reduces power consumption for battery-operated applications.

Audio Amplifiers Applications

• Portable media players
• Personal digital assistants (PDAs)
• Mobile phones

Audio Amplifiers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix and package variant matches design requirements. Review the official datasheet for absolute maximum ratings and thermal management guidelines. Ensure compliance with RoHS directives if applicable to the target market. Validate pinout configurations against PCB layout specifications prior to assembly.

Audio Amplifiers Selection Notes

Select this component for designs requiring a compact mono audio solution with minimal external components. The small 2x2 mm footprint suits space-constrained portable electronics. Evaluate thermal performance based on the exposed pad requirement for heat dissipation. Consider the single-supply operation range when designing the power architecture. Verify that the output power meets the speaker impedance and volume requirements.
