Overview
The TPA3111D1PWPR is a single-channel mono Class-D audio power amplifier manufactured by Texas Instruments. It delivers 10 W of continuous output power into an 8-ohm load with less than 0.5% total harmonic distortion plus noise (THD+N). The device operates on a single supply voltage ranging from 8 V to 26 V and features an analog input interface. It utilizes a 28-pin HTSSOP package and supports surface-mount installation. The operational temperature range spans from -40°C to +85°C, ensuring reliability in various environments.
Feature Summary
- Integrates SpeakerGuard technology for comprehensive protection against short circuits, over-temperature conditions, and pop-and-click suppression during startup and shutdown.
Applications
- Portable multimedia speakers
- Home theater systems
- Personal computer audio modules
Procurement Notes
Verify the specific datasheet revision and package marking codes before procurement. Confirm that the HTSSOP-28 footprint matches the target PCB layout. Ensure compatibility with the required 8 V to 26 V supply rails and 8-ohm load impedance specifications for the intended application design.
Selection Notes
Select this component when a high-efficiency mono amplifier is required for 8-ohm loads within an 8 V to 26 V supply range. It is suitable for designs prioritizing filter-free operation and integrated thermal and short-circuit protection. Consider alternative models if stereo output or higher power ratings are necessary.
Part Context
This part belongs to the TPA311x series of filter-free Class-D amplifiers. It shares architectural similarities with the TPA3112D1 but offers lower power output. The PWPR suffix indicates a tape-and-reel packaging format suitable for automated surface-mount assembly processes.
FAQ
Does the TPA3111D1PWPR require external output filters?
No, the device is designed as a filter-free amplifier, eliminating the need for external LC output filters.
What protection features are included in this amplifier?
It includes SpeakerGuard technology providing short-circuit protection, over-temperature protection, and pop-and-click suppression.
