TPA6111A2DGNRG4

Audio Amplifiers Overview

The TPA6111A2DGNRG4 is a stereo headphone audio amplifier manufactured by Texas Instruments. It operates in Class-AB topology and delivers 150 mW of output power into a 16 Ohm load. The device functions with a single power supply ranging from 2.5 V to 5.5 V. Total Harmonic Distortion plus Noise (THD+N) is specified at 0.6%. The unit draws 1.6 mA of operating current and supports a shutdown mode. It is housed in an 8-pin MSOP-PowerPad package and operates within a temperature range of -40°C to +85°C.

Audio Amplifiers Feature Summary

• Stereo headphone amplification with integrated shutdown control
• Pin-compatible design for LM4880 and LM4881 replacements
• Low quiescent current operation for battery efficiency

Audio Amplifiers Applications

• Portable media players
• Mobile phones
• Personal digital assistants

Audio Amplifiers Procurement Notes

Verify the suffix 'G4' indicates lead-free and RoHS compliance per Texas Instruments standards. Confirm the MSOP-PowerPad package type matches the target PCB footprint. Ensure the voltage rating aligns with the system's single-supply rails between 2.5 V and 5.5 V. Cross-reference the datasheet revision date to ensure compatibility with existing design files.

Audio Amplifiers Selection Notes

Select this component when a direct pin-for-pin replacement for LM4880 or LM4881 is required in stereo applications. It is suitable for designs needing low power consumption and moderate output power into 16 Ohm loads. Consider the MSOP-PowerPad package for thermal management and space-constrained layouts. Verify that the 2.5 V minimum supply voltage meets the system's lowest operating condition.

Audio Amplifiers Part Context

This part belongs to the TPA6111A2 series of stereo headphone amplifiers. It is designed as a drop-in replacement for legacy National Semiconductor parts, specifically the LM4880 and LM4881. The series focuses on portable audio applications requiring high sound quality with minimal external components. The DGNR variant specifies the MSOP-PowerPad package with reel packaging.

Audio Amplifiers Replacement Considerations

The TPA6111A2DGNRG4 is officially documented as pin-compatible with the LM4880 and LM4881. Designers replacing these legacy parts should verify that the new part's electrical characteristics meet the original circuit requirements.
