Overview
The TAS5111ADAD is a digital amplifier power stage from Texas Instruments, housed in a 32-pin TSSOP PowerPAD package. It delivers up to 70 W RMS into 4 Ω loads with less than 0.2% THD+N and over 90% efficiency. The device operates with a 3.3 V digital interface and utilizes PurePath Digital technology alongside a PWM processor. It features built-in self-protecting design with autorecovery, undervoltage protection, and overtemperature warning.
Feature Summary
- High-efficiency digital amplification exceeding 90% into standard speaker loads
- Integrated self-protecting architecture with automatic recovery from fault conditions
- Compatible with TI PurePath Digital technology for high-quality audio output
- Includes dedicated overtemperature warning and shutdown signaling outputs
Applications
- DVD Receivers
- Home Theatre Systems
- Mini/Micro Component Systems
- Internet Music Appliances
Procurement Notes
Verify the specific suffix ADAD confirms the 32-pin TSSOP PowerPAD package and commercial temperature range. Confirm compatibility with the required front-end PWM processor, such as the TAS5026, for proper system operation. Ensure the ordering information matches the exact thermal and electrical requirements of the target application design.
Selection Notes
Select this component when designing systems requiring high-power digital amplification with minimal external filtering complexity. Consider the thermal management requirements associated with the exposed pad package. Verify that the system can accommodate the necessary passive demodulation filter components to meet EMI and performance specifications.
Part Context
This part belongs to the TAS51xx series of digital amplifier power stages designed by Texas Instruments. It is engineered to work in conjunction with digital audio PWM processors to form a complete TDAA (Texas Instruments Digital Audio Amplifier) solution. The series focuses on delivering high fidelity and efficiency in compact consumer audio formats.
Replacement Considerations
Datasheet references TAS5111A as the base model. Verify if TAS5111ADADG4 or TAS5111ADADR are suitable equivalents based on packaging and tape/reel requirements.
