TPA2080D1YZGT

Overview

The TPA2080D1YZGT is a high-efficiency mono Class-D audio power amplifier featuring an integrated Class-G boost converter. It delivers 2.2 W of constant output power into a 4-ohm load with a fixed gain of 20 dB. The device operates on a supply voltage range of 2.5 V to 5.2 V and includes differential inputs for noise immunity. It is housed in a compact 12-DSBGA package, designed for space-constrained portable applications.

Feature Summary

• Integrates a Class-G boost converter to enhance overall system efficiency
• Provides constant output power regulation across varying supply voltages
• Features differential inputs to reject common-mode noise
• Includes built-in short-circuit and thermal protection mechanisms

Applications

• Portable media players
• Mobile phones
• Personal digital assistants

Procurement Notes

Verify the specific suffix YZGT to confirm the 12-DSBGA package type and tape-and-reel delivery format. Ensure compatibility with the required 2.5 V to 5.2 V operating voltage range. Confirm that the fixed 20 dB gain meets the system signal chain requirements without additional amplification stages.

Selection Notes

Select this component when a single-channel solution with integrated boost capability is required. It is suitable for designs prioritizing efficiency and constant power output over variable gain flexibility. Consider the small footprint if board space is limited. Verify that the thermal performance within the DSBGA package meets the application's heat dissipation needs.

Part Context

This part belongs to Texas Instruments' TPA2080 series of Class-D audio amplifiers. The series focuses on high-efficiency solutions for portable electronics. The TPA2080D1 variant specifically offers mono output with integrated boost, distinguishing it from variants without boost converters or those offering stereo outputs.

Replacement Considerations

Check the TPA2025D1YZGT as a potential alternative within the same family. Both share similar packaging and operational characteristics. Verify pin-to-pin compatibility and electrical parameter alignment before substitution.
