TPA6205A1DGNR

Overview

The TPA6205A1DGNR is a single-channel mono Class-AB audio amplifier manufactured by Texas Instruments. It delivers 1.25 W of output power into an 8-ohm load with a total harmonic distortion plus noise of 0.06%. The device operates on a single power supply ranging from 2.5 V to 5.5 V and draws a quiescent current of 1.7 mA. It features fully differential inputs and is housed in an MSOP-PowerPad-8 package, suitable for surface-mount installation across a temperature range of -40°C to +85°C.

Feature Summary

• Fully differential analog input architecture for improved noise rejection
• Class-AB topology providing high-fidelity audio reproduction
• Integrated thermal shutdown protection for operational safety

Applications

• Portable media players
• Mobile handsets
• Personal digital assistants

Procurement Notes

Verify the specific suffix DGNR against the manufacturer's official datasheet to confirm the MSOP-PowerPad-8 packaging and reel quantity specifications. Ensure compatibility with single-supply voltage rails between 2.5 V and 5.5 V. Confirm RoHS compliance status through the latest component documentation before integration.

Selection Notes

Select this component for designs requiring a compact mono amplifier with low quiescent current consumption. The fully differential input stage simplifies interface requirements compared to single-ended alternatives. Verify that the 8-ohm load impedance matches the target speaker configuration to achieve the specified 1.25 W output performance.

Part Context

This part belongs to the TPA6205A1 series of audio amplifiers designed for portable electronics. It shares the same core amplifier architecture as other variants in the family but differs in packaging and specific electrical characteristics defined by the DGNR suffix.

Replacement Considerations

Consult the manufacturer's cross-reference guide for verified substitutes. Direct replacements must maintain Class-AB operation, similar power output, and compatible MSOP-PowerPad-8 footprints.
