TPA6204A1DRBG4

Overview

The TPA6204A1DRBG4 is a single-channel mono Class-AB audio power amplifier manufactured by Texas Instruments. It delivers 1.7 W of output power into an 8-ohm load with a total harmonic distortion plus noise of 0.02%. 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 fully differential inputs and is housed in an 8-pin SON package. The component supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Fully differential input architecture for improved noise rejection
• High efficiency Class-AB operation delivering up to 1.7 W output
• Low total harmonic distortion plus noise of 0.02%
• Single-supply operation compatible with standard battery voltages

Applications

• Portable multimedia devices requiring high-fidelity audio
• Mobile phones and smartphones
• Personal digital assistants (PDAs)
• MP3 players and portable media players

Procurement Notes

Verify the specific suffix G4 indicates lead-free and RoHS compliance status against the manufacturer's latest documentation. Confirm the SON-8 package dimensions match your PCB footprint requirements. Ensure the differential input configuration aligns with your source circuit design. Check for any moisture sensitivity level restrictions during storage and handling procedures.

Selection Notes

Select this component when a single-channel mono amplifier with fully differential inputs is required. It is suitable for applications needing 1.7 W output power into 8-ohm loads. Consider the 4 mA quiescent current for battery life optimization. Verify that the 2.5 V to 5.5 V supply range matches your system voltage. The SON-8 package is appropriate for space-constrained designs.

Part Context

This part belongs to the TPA6204A1 series of audio amplifiers from Texas Instruments. The series focuses on providing high-quality audio performance in compact packages. The TPA6204A1DRBG4 variant specifically utilizes the DRB package code, indicating an 8-pin SON form factor. It is designed for portable consumer electronics where size and power efficiency are critical constraints.

Replacement Considerations

The TPA6204A1DRBRG4 is a direct functional substitute within the same family, differing primarily in reel packaging instead of tube. Both share identical electrical specifications and pinouts. Verify package compatibility before substitution.
