TPA0211DGN

Overview

The TPA0211DGN is a single-channel Class-AB audio power amplifier designed for driving low-impedance speakers. It delivers 2W output into a 4Ω load at 5V supply and 0.6W at 3V. The device operates on a single supply voltage ranging from 2.5V to 5.5V. It features a shutdown mode with typical current consumption of 1µA, while active operation draws approximately 4mA. The amplifier supports both Single-Ended (SE) and Bridge-Tied Load (BTL) configurations via an external control pin. It is housed in an 8-pin MSOP PowerPAD package suitable for thermal management.

Feature Summary

• Supports flexible SE/BTL mode switching for optimized speaker or headphone drive applications
• Integrated shutdown control significantly reduces standby power consumption
• Thermal-enhanced MSOP PowerPAD package facilitates heat dissipation in compact designs

Applications

• Driving internal mono speakers in mobile phones and wireless communication devices
• Powering small loudspeakers in personal digital assistants (PDAs)
• Audio output stages in laptop computers and portable media players

Procurement Notes

Verify the specific suffix 'DGN' corresponds to the tube packaging variant rather than the 'DGNG4' RoHS-compliant version or the 'DGNR' reel variant. Confirm the manufacturer date code and lot traceability requirements against your quality standards. Ensure the ordering part number matches the exact package outline and thermal pad specifications required by your PCB layout.

Selection Notes

Select this component when a single-supply, low-voltage solution is required for driving 4Ω loads without complex biasing networks. The fixed internal gain settings simplify circuit design compared to programmable amplifiers. Consider the BTL capability if higher power output is needed within the same voltage rail constraints. Evaluate the thermal performance of the PowerPAD package relative to your enclosure's heat dissipation capabilities.

Part Context

This part belongs to Texas Instruments' TPA0211 family of efficient mono audio power amplifiers. The family includes variants such as TPA0211DGNG4 and TPA0211DGNR, which share identical electrical characteristics but differ in packaging format and environmental compliance certifications. The DGN designation specifically identifies the non-reel, tube-packaged unit within this product line.

Replacement Considerations

Direct functional substitutes include TPA0211DGNG4 and TPA0211DGNR. These parts maintain identical pinouts and electrical specifications. Verify that the replacement variant meets any specific regulatory requirements, such as RoHS compliance, which may necessitate the G4 suffix.
