Overview
The TPA2026D2YZHR 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 3.2W per channel into a 4-ohm load. The device features a 16-pin DSBGA package measuring 2.24x2.16mm. It supports differential inputs and includes integrated I2C control for volume adjustment. Thermal and short-circuit protection are built-in, with an operating temperature range of -40°C to 85°C.
Feature Summary
- Integrates SmartGain technology for simplified gain configuration and volume control via I2C interface.
- Provides high-efficiency stereo amplification using Class-D topology with differential input capability.
- Includes comprehensive protection mechanisms such as thermal shutdown and short-circuit current limiting.
Applications
- Portable multimedia devices requiring efficient stereo audio output
- Smart home speakers and voice-controlled assistants
- Automotive infotainment systems
Procurement Notes
Verify the specific suffix YZHR corresponds to the 16-DSBGA package and reel packaging format. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Ensure design compatibility with the required supply voltage range and thermal dissipation requirements for the target application environment.
Selection Notes
Select this component when a compact stereo solution with digital control is needed. The 16-DSBGA footprint suits space-constrained designs. Consider the I2C interface requirement for volume management. Evaluate power output needs against the 4-ohm load specification to ensure adequate performance margins.
Part Context
This part belongs to the TPA2026 family of audio amplifiers. It is designed for low-voltage applications where efficiency and small form factor are critical. The SmartGain feature distinguishes it by allowing software-adjustable gain settings, reducing external component count compared to fixed-gain alternatives.
Replacement Considerations
Check for pin-compatible upgrades within the TPA202x series. Verify if alternative packages like DSBGA-14 or DSBGA-16 variants offer similar electrical characteristics. Ensure any substitute maintains I2C controllability and meets the same thermal protection standards.
