Overview
The TPA3005D2PHPR is a stereo Class-D audio amplifier manufactured by Texas Instruments, housed in a 48-pin HTQFP package. It delivers 6 W of output power into an 8-ohm load with a total harmonic distortion plus noise of 0.1%. The device operates on a single supply voltage ranging from 8.5 V to 18 V and functions within a temperature range of -40°C to +85°C. It features analog inputs, draws 11 mA of quiescent current, and includes shutdown functionality.
Feature Summary
- Filter-free Class-D architecture eliminates the need for external output filters.
- Integrated thermal and short-circuit protection mechanisms ensure operational reliability under fault conditions.
- Supports analog input signals with configurable gain settings.
Applications
- Portable multimedia speakers
- Home theater systems
- Automotive infotainment audio modules
Procurement Notes
Verify the specific suffix 'PHPR' corresponds to the HTQFP-48 package and reel packaging configuration. Confirm RoHS compliance status and moisture sensitivity level requirements prior to assembly. Ensure the ordering part number matches the exact pinout and electrical specifications defined in the official datasheet to avoid integration errors.
Selection Notes
Select this component when a compact stereo solution is required for applications demanding moderate power output around 6 watts. It is suitable for designs constrained by space due to its filter-free topology. Consider the 8.5 V to 18 V supply range compatibility with existing system power rails before finalizing the design.
Part Context
This device belongs to the TPA3005D2 series of high-performance audio amplifiers. It shares architectural similarities with other members like the TPA3004D2 but offers distinct power output characteristics tailored for specific stereo applications. The series emphasizes efficiency and sound quality in a small form factor.
Replacement Considerations
The TPA3005D2PHT is a pin-compatible alternative available in a different package variant. Verify mechanical footprint differences and thermal performance requirements when substituting between PHPR and PHT packages.
