TPA6211A1DGN

Overview

The TPA6211A1DGN is a mono, fully differential Class-AB audio amplifier manufactured by Texas Instruments. It delivers 3.1 W of continuous output power into a 3-ohm load with a supply voltage range of 2.5 V to 5.5 V. The device features a total harmonic distortion plus noise (THD+N) of 0.06% and operates with a quiescent current of 4 mA. It utilizes an MSOP-PowerPad-8 package suitable for surface-mount applications across a temperature range of -40°C to +85°C.

Feature Summary

• Fully differential input architecture provides high common-mode rejection ratio for improved noise immunity in single-supply systems.
• Integrated thermal protection circuitry safeguards the device against overheating during high-power operation or fault conditions.
• Capable of delivering high output power efficiency while maintaining low harmonic distortion for high-fidelity audio reproduction.

Applications

• Portable multimedia speakers
• MP3 players and digital audio players
• Personal computers and monitors

Procurement Notes

Verify the specific suffix 'DGN' corresponds to the MSOP-PowerPad-8 tube packaging variant rather than reel-based alternatives like DRBR. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability fluctuates. Ensure the design supports the required single-supply voltage range and thermal dissipation for the selected enclosure.

Selection Notes

Select this component when a single-ended to differential conversion is required without external transformers. It is appropriate for designs needing moderate power output in compact form factors. Compare against the TPA6203A1 if lower power consumption is prioritized over maximum output capability. Verify that the PCB layout accommodates the exposed power pad for adequate heat sinking.

Part Context

This part belongs to the TPA6211A1 family of mono audio amplifiers designed for portable consumer electronics. It serves as a bridge between line-level sources and low-impedance speakers. The series includes variants with different packaging options such as SON and HVSSOP to suit various board space constraints.

Replacement Considerations

TPA6211A1DGNG4 is a verified equivalent offering identical electrical specifications and functionality within the same MSOP package family.
