Overview
The TPA3002D2PHPR is a stereo Class-D audio power amplifier manufactured by Texas Instruments. It delivers 9 W of continuous output power into an 8-ohm load with a supply voltage range of 8.5 V to 14 V. The device features a total harmonic distortion plus noise (THD+N) of 0.025% and operates on a single power supply. It utilizes a differential input configuration and includes a shutdown function for power management. The component is housed in a 48-pin HTQFP package, suitable for surface-mount installation, and functions within a temperature range of -40°C to +85°C.
Feature Summary
- Filter-free Class-D architecture eliminates the need for external output filters.
- Integrated volume control functionality simplifies system design.
- Low total harmonic distortion ensures high-fidelity audio reproduction.
Applications
- Liquid crystal display televisions
- Home theater systems
- Portable audio devices
Procurement Notes
Verify the complete part number including the suffix 'PR' to confirm the reel packaging specification. Ensure compatibility with the required 48-pin HTQFP footprint during PCB layout. Confirm that the application environment remains within the specified operating temperature limits. Validate that the power supply voltage does not exceed the maximum rating of 14 V to prevent device damage.
Selection Notes
Select this component when a compact stereo amplifier solution is required for medium-power applications. It is appropriate for designs where filter-free operation reduces bill of materials cost. Consider the 8.5 V to 14 V supply range when designing the power stage. Verify that the 9 W output power meets the specific speaker requirements of the target application.
Part Context
This device belongs to the TPA3002D2 family of audio amplifiers from Texas Instruments. It shares the same HTQFP-48 package form factor as other members like the TPA3004D2 and TPA3100D2 series. These components are designed for consumer electronics requiring efficient, high-quality sound amplification without complex external filtering networks.
Replacement Considerations
The TPA3002D2PHPG4 is a lead-free variant of this component. Verify pinout and electrical specifications before substitution. Other family members such as the TPA3004D2 offer different power ratings but share similar packaging.
