Overview
The TPA6211A1DRBR 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 an 8-pin SON package (3x3 mm) and supports operation within a temperature range of -40°C to +85°C.
Feature Summary
- Fully differential input architecture for improved noise rejection
- Integrated pop-and-click suppression circuitry
- Built-in thermal protection to prevent overheating
- Low quiescent current consumption for battery efficiency
Applications
- Portable media players
- Mobile phones
- Personal digital assistants
- MP3 players
Procurement Notes
Verify the specific suffix DRBR corresponds to the 8-SON 3x3mm package and reel packaging configuration. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the ordering part number matches the exact revision and tape-and-reel specifications required for automated placement equipment.
Selection Notes
Select this component when a high-efficiency mono amplifier is needed for low-voltage portable systems. The fully differential input simplifies interface design with source components. Consider the 8-SON package size for space-constrained PCB layouts. Verify that the 3.1W output capability meets the speaker impedance and volume requirements of the target application.
Part Context
This part belongs to the TPA6211A1 series of audio amplifiers. It is designed for mobile and portable applications requiring high sound quality in a small form factor. The series includes variants with different packages, such as the DGNR in a TSSOP-8 package, offering flexibility for various board designs while maintaining similar electrical performance characteristics.
Replacement Considerations
The TPA6211A1DRBRG4 is a verified lead-free variant of the same functional device. Other members of the TPA6211A1 family may serve as alternatives if package differences are acceptable. Verify pin compatibility and thermal performance before substituting with other mono Class-AB amplifiers.
