Overview
The TPA2016D2YZHR is a stereo Class-D audio amplifier from Texas Instruments, part of the SmartGain series. It operates on a supply voltage range of 2.5V to 5.5V and delivers up to 2.8W per channel into a 4-ohm load. The device features differential inputs, I2C control for volume and AGC, and includes short-circuit and thermal protection. It is housed in a compact 16-WFQFN (4x4) surface-mount package suitable for portable applications.
Feature Summary
- Integrates an automatic gain control engine with programmable limiting for dynamic range management
- Supports digital volume control and shutdown modes via I2C interface
- Includes built-in thermal and short-circuit protection mechanisms
Applications
- Smart voice nodes and IoT audio devices
- Portable consumer electronics requiring low power consumption
- Embedded speaker systems with limited space constraints
Procurement Notes
Verify the specific suffix YZHR against the manufacturer datasheet to confirm the 16-WFQFN package variant. Ensure compatibility with the required I2C address configuration and check RoHS3 compliance status before finalizing procurement specifications.
Selection Notes
Select this component when designing battery-powered audio systems that require integrated signal processing. The inclusion of on-chip AGC reduces the need for external DSPs. Verify that the system power supply remains within the 2.5V to 5.5V operating range for optimal performance.
Part Context
This model belongs to the TPA2016 family of high-efficiency stereo amplifiers. It is designed to replace traditional analog volume controls by offering precise digital adjustment. The device targets markets demanding high sound quality in minimal form factors, such as wearable technology and smart home assistants.
Replacement Considerations
Consult official substitution guides for pin-compatible alternatives. Verify that any replacement maintains the same 16-pin QFN footprint and supports the required I2C communication protocol for seamless integration.
