Overview
The TPA3112D1PWP is a mono Class-D audio amplifier manufactured by Texas Instruments. It delivers 25 W of output power into an 8-ohm load with a total harmonic distortion plus noise of 0.05%. The device operates on a single supply voltage ranging from 8 V to 26 V and draws a typical operating current of 40 mA. It features differential analog inputs and is housed in a 28-pin HTSSOP package. The component supports surface mount installation and functions within a temperature range of -40°C to +85°C.
Feature Summary
- Filter-free design eliminates the need for external output filters.
- Integrated SpeakerGuard protection prevents speaker damage during power-up, power-down, and fault conditions.
- Supports differential input signals for improved noise immunity.
Applications
- Audio equipment
- Televisions
Procurement Notes
Verify the specific suffix 'PWP' corresponds to the tube packaging format rather than reel or cut tape options when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected variant matches the required thermal performance and pinout configuration for the target PCB layout.
Selection Notes
Select this component for high-power mono applications requiring efficient amplification without bulky output filtering. Consider the 28-pin HTSSOP package dimensions for board space constraints. Evaluate the 8 V to 26 V supply range against system power availability. Verify that the 0.05% THD+N specification meets the audio fidelity requirements of the end product.
Part Context
This part belongs to the TPA3112D1 series of high-efficiency audio amplifiers. It shares the same core architecture as the TPA3112D1PWPR but differs in packaging. The series utilizes Texas Instruments' SpeakerGuard technology for robust operation. It serves as a direct replacement for previous generation filter-based mono amplifiers in consumer electronics.
Replacement Considerations
The TPA3112D1PWPR is a functional equivalent differing only in packaging format (reel versus tube). No other direct substitutes are confirmed in the provided data.
