TPA2031D1YZFT

Overview

The TPA2031D1YZFT is a 2.5-W mono Class-D audio power amplifier in a 9-pin DSBGA package. It operates on a supply voltage range of 2.5 V to 5.5 V and supports an 8-ohm load. The device delivers high efficiency with 88% performance and features a THD+N of 0.18%. It includes a 32 ms start-up time to eliminate codec click/pop noise and offers -75-dB PSRR. Operating temperatures range from -40°C to +85°C.

Feature Summary

• Filter-free design eliminates external output filters
• Slow start-up feature prevents audible click/pop noise
• High power conversion efficiency for extended battery life
• Pin-to-pin compatible with TPA2010D1

Applications

• Portable media players
• Mobile phones
• Personal digital assistants
• MP3 players

Procurement Notes

Verify the exact suffix YZFT confirms the 9-DSBGA package and tape-and-reel or cut-tape delivery format as specified by Texas Instruments. Ensure RoHS compliance and lead-free status match project requirements. Cross-reference the manufacturer part number against official TI databases to confirm availability and current production status before finalizing procurement orders.

Selection Notes

Select this component for applications requiring a compact, single-channel audio solution without external filtering components. The 9-DSBGA package suits space-constrained designs. Consider the 32 ms start-up delay when designing system power sequencing to ensure it aligns with user experience expectations regarding audio initialization delays.

Part Context

This device belongs to Texas Instruments' NanoFree series of audio amplifiers. It is designed to replace legacy filter-based amplifiers while maintaining similar pinouts to older models like the TPA2010D1. The series focuses on maximizing battery life and minimizing thermal dissipation in portable consumer electronics through high-efficiency Class-D topology.

Replacement Considerations

The TPA2010D1 is documented as pin-to-pin compatible. Verify that the specific application constraints regarding start-up timing and filter requirements are met by both devices before substitution.
