TPA2016D2YZHT

Overview

The TPA2016D2YZHT is a stereo 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 2.8 W per channel into a 4-ohm load. The device features differential analog inputs, I²C control interface, and integrated automatic gain control (AGC). It includes comprehensive protection mechanisms such as thermal shutdown and short-circuit protection. The component is housed in a compact 16-DSBGA package with dimensions of 2.24 mm by 2.16 mm.

Feature Summary

• Integrates an I²C-controlled automatic gain control engine for dynamic input signal management without external digital signal processing.
• Supports inductor-free operation utilizing spread spectrum technology to minimize electromagnetic interference.
• Provides robust speaker protection through built-in power limiting and DC detection circuits.

Applications

• Smart voice terminals
• IoT audio alarm devices
• Educational acoustic experiment platforms

Procurement Notes

Verify the specific suffix 'YZHT' against official manufacturer documentation to confirm exact reel packaging quantities and moisture sensitivity levels. Ensure compatibility with standard I²C logic levels when integrating with microcontrollers operating at 3.3 V or 5 V. Confirm that the selected variant matches the required thermal performance for the intended enclosure design.

Selection Notes

Select this component for applications requiring high efficiency and low power consumption in battery-operated portable devices. The integrated AGC functionality simplifies audio chain design by automatically adjusting gain to prevent clipping. Consider the small footprint when space constraints are critical, and ensure the system supports I²C communication for volume and mode configuration.

Part Context

This part belongs to the TPA2016 family of smart audio amplifiers designed for portable consumer electronics. It combines power amplification with intelligent signal processing capabilities. The family is characterized by its ability to deliver high-quality audio output while maintaining low total harmonic distortion and noise levels across various supply voltages.

Replacement Considerations

Consult official substitution guides for pin-compatible alternatives within the same product family. Verify that any replacement maintains the required I²C address and register map if software reuse is intended.
