TPA2015D1YZHT

Overview

The TPA2015D1 is a mono Class-D audio power amplifier manufactured by Texas Instruments. It features an integrated adaptive boost converter and SpeakerGuard AGC technology to optimize efficiency and prevent clipping. The device delivers up to 2W of output power into an 8-ohm load with 6% THD+N when powered by a 3.6V supply. Operating voltage ranges from 2.5V to 5.2V, with a typical quiescent current of 1.7mA at 3.6V. It utilizes a DSBGA package (YZH) measuring 1.954mm x 1.954mm with a 0.5mm pitch.

Feature Summary

• Integrates an adaptive boost converter to enhance efficiency at low output power levels.
• Includes SpeakerGuard automatic gain control to limit battery current draw and prevent severe audio clipping.
• Features a built-in low-pass filter for improved RF rejection and reduced DAC out-of-band noise.

Applications

• Mobile phones
• Personal Digital Assistants (PDAs)
• GPS devices
• Portable electronic equipment

Procurement Notes

Verify the specific suffix 'YZHT' against official Texas Instruments documentation to confirm tape-and-reel packaging and temperature grade specifications. Ensure compatibility with existing PCB footprints designed for the YZH DSBGA package dimensions. Cross-reference thermal requirements for the intended application environment.

Selection Notes

Select this component for battery-powered applications requiring high efficiency and compact form factors. The integrated boost converter allows operation from lower voltage sources while maintaining higher output power compared to direct-drive amplifiers. Consider the fixed gain options and protection features when designing for portable consumer electronics.

Part Context

This part belongs to the TPA201xD1 series of single-channel Class-D audio amplifiers. It is pin-to-pin compatible with the TPA2013D1 model, facilitating design upgrades or replacements within existing TI-based audio architectures without requiring schematic modifications.

Replacement Considerations
