LM4930ITL/NOPB

Audio Amplifiers Overview

The LM4930ITL/NOPB is a Class-AB mono audio amplifier manufactured by Texas Instruments. It operates within a supply voltage range of 2.6 V to 5.5 V and delivers up to 1 W of output power. The device utilizes a 36-pin WFBGA package for surface mount installation. It supports an operating temperature range from -40°C to +85°C. Key electrical characteristics include integrated digital control interfaces and low quiescent current consumption suitable for portable applications.

Audio Amplifiers Feature Summary

• Integrates I2S, PCM, and DAC interfaces for direct digital audio input connectivity
• Includes built-in depop circuitry to eliminate startup and shutdown pop noise
• Supports differential inputs for improved noise immunity in audio signal paths

Audio Amplifiers Applications

• Portable media players requiring high-fidelity mono audio output
• Mobile handsets utilizing digital microphone or codec interfaces
• Embedded audio subsystems with strict space constraints

Audio Amplifiers Procurement Notes

Verify the specific suffix 'ITL' corresponds to the required 36-pin WFBGA package variant. Confirm RoHS compliance status through official manufacturer documentation. Ensure the ordering part number matches the exact thermal and mechanical specifications required for your PCB layout design.

Audio Amplifiers Selection Notes

Select this component when a single-channel high-power amplifier is needed alongside digital audio interface integration. It is suitable for designs requiring I2S or PCM connectivity without external digital-to-analog conversion stages. Consider the WFBGA footprint availability during the initial schematic capture phase.

Audio Amplifiers Part Context

This device belongs to the LM4930 family of audio subsystems designed for mobile and portable electronics. It combines a Class-AB power amplifier with digital control logic to simplify system architecture. The NOPB suffix indicates lead-free and RoHS-compliant manufacturing standards consistent with Texas Instruments environmental policies.

Audio Amplifiers Replacement Considerations

Consult official substitution guides for pin-compatible alternatives within the LM49xx series. Verify that any substitute maintains identical I2S/PCM interface timing and WFBGA-36 package dimensions.
