TPA2039D1YFFR

Overview

The TPA2039D1YFFR is a single-channel mono Class-D audio amplifier manufactured by Texas Instruments. It delivers 3.2 W of continuous output power into a 4-ohm load with a supply voltage range of 2.5 V to 5.5 V. The device features a fixed gain architecture and maintains a total harmonic distortion plus noise (THD+N) of 0.32%. It operates within an ambient temperature range of -40°C to +85°C and draws a typical operating supply current of 1.8 mA. The component is housed in a compact 9-pin DSBGA package.

Feature Summary

• Class-D topology for high efficiency
• Integrated differential input stage
• Built-in short-circuit and thermal protection mechanisms
• Shutdown mode capability for power management

Applications

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

Procurement Notes

Verify the specific suffix YFFR against the manufacturer's datasheet to confirm the tape-and-reel packaging configuration. Ensure the ordering part number matches the required pinout and package dimensions for your PCB layout. Confirm RoHS compliance status through official documentation before finalizing procurement specifications.

Selection Notes

Select this component when a single-channel, fixed-gain solution is required for space-constrained portable designs. The DSBGA package supports dense board layouts. Verify that the application load impedance aligns with the 4-ohm specification to achieve the rated 3.2 W output power without exceeding thermal limits.

Part Context

This part belongs to the TPA2039D1 series of nano-free audio amplifiers. It is designed specifically for battery-powered applications requiring high sound quality and minimal external components. The series integrates all necessary control logic and protection circuits into a small footprint suitable for modern mobile electronics.

Replacement Considerations

The TPA2037D1YFFR is a confirmed substitute within the same family, offering identical electrical performance and pinout compatibility.
