TPA0211DGNG4

Overview

The TPA0211DGNG4 is a single-channel mono Class-AB audio amplifier manufactured by Texas Instruments. It delivers 2 W of output power into a 4 Ohm load at 5 V supply voltage 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. Total Harmonic Distortion plus Noise is specified at 0.2%. It utilizes an 8-pin MSOP-PowerPad package and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Supports flexible switching between Single-Ended (SE) and Bridge-Tied Load (BTL) modes via a dedicated control pin.
• Features low-power shutdown capability with typical standby current of 1 µA to extend battery life in portable devices.
• Includes integrated thermal protection circuitry to safeguard the component during high-power operation or overheating conditions.

Applications

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

Procurement Notes

Verify the suffix G4 indicates RoHS compliance and lead-free construction as per Texas Instruments standards. Confirm the MSOP-PowerPad-8 package type matches your PCB footprint requirements. Ensure the single-ended analog input configuration aligns with your system design, as this variant does not support differential inputs.

Selection Notes

Select this component for applications requiring a simple mono audio solution with moderate power output. It is suitable for designs where space is limited due to its compact 8-pin package. Consider the SE/BTL mode flexibility if the design requires driving either a speaker or headphones without additional external components.

Part Context

This part belongs to the TPA0211 series of efficient mono audio power amplifiers. It is designed specifically for driving low-impedance loads such as 4Ω speakers. The DGNG4 designation specifies the tube packaging variant, distinct from the DGNR reel version, while maintaining identical electrical characteristics and functionality.

Replacement Considerations

TPA0211DGN is the non-RoHS equivalent with identical electrical specifications but different packaging options. TPA0211DGNG4 is the direct RoHS-compliant replacement for earlier versions. Other TPA series amplifiers may offer higher power or differential inputs but require different circuit configurations.
