TPA0211DGNRG4

Overview

The TPA0211DGNRG4 is a single-channel mono Class-AB audio power amplifier manufactured by Texas Instruments. It delivers 2 W of output power into a 4 Ω load at a 5 V supply and 0.6 W at 3 V. The device operates on a single power supply ranging from 2.5 V to 5.5 V with a typical quiescent current of 4 mA. It features a total harmonic distortion plus noise (THD+N) of 0.2% and supports both single-ended and bridge-tied load configurations. The component is housed in an 8-pin MSOP-PowerPad package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Supports flexible switching between single-ended and bridge-tied load modes via a dedicated control pin.
• Integrates internal feedback resistors allowing user-defined gain settings through external input resistors.
• Includes shutdown functionality that reduces operating current to approximately 1 µA for extended battery life.

Applications

• Driving low-impedance speakers in mobile phones and wireless communication devices
• Powering mono loudspeakers in laptops and personal digital assistants
• Providing direct headphone drive capability without requiring additional amplification stages

Procurement Notes

Verify the G4 suffix indicates RoHS compliance and lead-free construction per manufacturer standards. Confirm the MSOP-PowerPad-8 package matches your PCB footprint requirements. Ensure the thermal pad connection is properly designed for heat dissipation given the PowerPAD structure. Cross-reference the datasheet revision to confirm electrical characteristics align with your design specifications.

Selection Notes

Select this component when a single-channel mono amplifier is required for portable electronics. It is suitable for applications needing direct speaker or headphone driving capabilities. Consider the 4 Ω load impedance specification when designing the output stage. Evaluate the 2.5 V to 5.5 V supply voltage range against your system's power architecture.

Part Context

This part belongs to the TPA0211 series of high-efficiency mono audio power amplifiers. It is functionally equivalent to the TPA0211DGN, with the G4 suffix denoting environmental compliance. Both variants share identical electrical performance and pinout configurations within the same 8-pin MSOP-PowerPad package family.

Replacement Considerations

The TPA0211DGNG4 serves as a verified alternative offering identical electrical specifications and RoHS-compliant construction. Verify package compatibility before substitution.
