TPA2028D1YZFR

Overview

The TPA2028D1YZFR is a single-channel mono Class-D audio amplifier manufactured by Texas Instruments. It delivers 3 W of output power into a 4-ohm load with a total harmonic distortion plus noise of 1%. The device operates on a supply voltage ranging from 2.5 V to 5.5 V and draws a quiescent current of 3.5 mA. It functions within an ambient temperature range of -40°C to +85°C and utilizes a DSBGA-9 surface-mount package.

Feature Summary

• Integrates SmartGain technology for automatic gain control and dynamic range compression
• Supports digital volume control via I2C interface
• Includes protection mechanisms against short circuits and thermal overload

Applications

• Portable multimedia devices requiring high-efficiency audio amplification
• Smart home speakers and voice-controlled assistants
• Industrial audio equipment operating in wide temperature environments

Procurement Notes

Verify the specific suffix 'YZFR' corresponds to the reel packaging configuration required for your assembly line. Confirm that the design supports the I2C digital control interface, as this distinguishes it from non-digital variants. Ensure the PCB footprint matches the DSBGA-9 package dimensions specified in the official datasheet to prevent mounting errors during production.

Selection Notes

Select this component when a single-channel solution with integrated digital signal processing is necessary. It is suitable for applications where space is constrained due to its compact DSBGA-9 form factor. Consider this part over analog-only alternatives if system-level volume adjustment and dynamic range management are required without external microcontrollers or additional discrete components.

Part Context

This component belongs to the TPA2028D1 series, which focuses on delivering high-fidelity audio in small footprints. It is distinct from the TPA2029D1, which offers slightly higher power output but lacks the SmartGain features. The YZFT variant shares identical electrical characteristics but differs in tape-and-reel packaging quantity compared to the standard reel format.

Replacement Considerations

The TPA2028D1YZFT serves as a direct functional substitute with identical specifications, differing only in packaging type.
