TPA2038D1YFFR

Overview

The TPA2038D1YFFR is a single-channel mono Class-D audio amplifier manufactured by Texas Instruments. It operates within a supply voltage range of 2.5 V to 5.5 V and delivers up to 3.24 W of output power into a 4-ohm load. The device features a total harmonic distortion plus noise (THD+N) of 0.32% and draws a typical operating supply current of 1.8 mA. It is housed in a compact 9-pin DSBGA package and supports surface-mount installation. The component functions reliably across an extended temperature range from -40°C to +85°C.

Feature Summary

• Supports differential input configurations for improved noise immunity
• Integrates protection mechanisms including short-circuit and thermal shutdown
• Includes pop-and-click suppression circuitry to minimize audible artifacts during power transitions
• Features a dedicated shutdown pin for low-power management

Applications

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

Procurement Notes

Verify the specific suffix YFFR confirms the tape and reel packaging format required for automated assembly processes. Confirm that the RoHS compliance status aligns with regional environmental regulations applicable to the final product deployment. Ensure the ordering quantity meets the manufacturer's standard packaging multiples to avoid cut-tape handling requirements.

Selection Notes

Select this component when a fixed-gain, high-efficiency mono amplifier is required for battery-powered devices. The small DSBGA footprint makes it suitable for space-constrained designs where board real estate is limited. Consider the 2.5V to 5.5V operating range to ensure compatibility with single-cell lithium-ion battery systems or standard 5V logic supplies without additional regulation.

Part Context

This part belongs to the TPA2038D1 series of Class-D audio amplifiers designed for portable electronics. It serves as a cost-effective solution for delivering high-quality audio performance in mobile applications. The series is characterized by its ability to drive low-impedance loads efficiently while maintaining low power consumption.

Replacement Considerations

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