TPA2037D1YFFT

Overview

The TPA2037D1YFFT is a single-channel mono Class-D audio power amplifier manufactured by Texas Instruments. It operates within a supply voltage range of 2.5 V to 5.5 V and delivers up to 3.2 W of output power into a 4-ohm load. The device features a fixed gain configuration with a total harmonic distortion plus noise (THD+N) of 0.32%. It is housed in a compact 9-pin DSBGA package, suitable for surface-mount installation, and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Class-D architecture providing high efficiency for low-power audio applications
• Fixed gain design simplifying circuit integration without external feedback components
• Integrated protection mechanisms including thermal shutdown and short-circuit protection

Applications

• Portable media players
• Personal computers and monitors
• Laptop systems

Procurement Notes

Verify the specific suffix 'YFFT' against the manufacturer datasheet to confirm the tape-and-reel packaging format and pinout orientation. Ensure the ordering part number matches the exact package type required for your PCB footprint. Cross-reference the revision level to guarantee compatibility with existing design files.

Selection Notes

Select this component when a single-channel solution is required for battery-powered devices due to its efficient Class-D operation. The fixed gain characteristic reduces bill-of-materials complexity compared to programmable gain amplifiers. Consider the small DSBGA package size if board space is limited in portable consumer electronics designs.

Part Context

This part belongs to the TPA2037D1 series of low-power audio amplifiers. It shares functional similarities with other members like the TPA2039D1 but may differ in specific electrical characteristics or packaging options. The series targets mobile and portable audio markets requiring high sound quality in minimal form factors.

Replacement Considerations

The TPA2037D1YFFR is a verified substitute offering identical electrical performance with a reel packaging option instead of cut tape.
