TPA6211A1DRBRG4

Overview

The TPA6211A1DRBRG4 is a mono, fully differential Class-AB audio amplifier manufactured by Texas Instruments. It delivers 3.1 W of output power into a 3-ohm load with a total harmonic distortion plus noise of 0.06%. The device operates on a single supply voltage ranging from 2.5 V to 5.5 V and draws a typical quiescent current of 4 mA. It features a low-profile 8-SON (3x3 mm) package suitable for surface mount applications. The operational temperature range spans from -40°C to +85°C.

Feature Summary

• Fully differential input architecture provides high noise immunity and simplified interface requirements.
• Integrated pop-and-click suppression circuitry eliminates audible transients during power-up and power-down sequences.
• Built-in thermal protection safeguards the device against overheating under fault conditions.

Applications

• Portable media players
• Mobile phones
• Personal digital assistants

Procurement Notes

Verify the specific suffix G4 indicates RoHS compliance and green material status as per Texas Instruments standards. Confirm the DRBR designation corresponds to the tape and reel packaging format. Ensure the component matches the required 8-SON footprint and pinout for your PCB layout. Cross-reference the datasheet revision date to ensure compatibility with your design specifications.

Selection Notes

Select this component when a single-channel solution with fully differential inputs is required for space-constrained portable designs. The 3.1 W output capability at 3 ohms makes it suitable for driving small speakers in mobile devices. Consider the 8-SON package dimensions if board real estate is limited. Verify that the 2.5 V to 5.5 V supply range aligns with your system's battery or power rail characteristics.

Part Context

This part belongs to the TPA6211A1 family of audio amplifiers from Texas Instruments. The family includes variants such as TPA6211A1DRBG4 and TPA6211A1DGNRG4, which differ primarily in packaging type. The TPA6211A1 series is designed for high-efficiency, low-power audio applications in consumer electronics. It shares core functional characteristics with other members of the series while offering specific packaging options for different manufacturing needs.

Replacement Considerations

TPA6211A1DRBR is the non-RoHS compliant equivalent. TPA6211A1DRBG4 offers the same functionality in a tube package. TPA6211A1DGNRG4 utilizes an 8-TSSOP package instead of SON. Verify pin-to-pin compatibility and thermal performance before substituting.
