Overview
The TPA3004D2PHPR is a stereo high-power filter-free Class-D audio amplifier manufactured by Texas Instruments. It delivers 12 W of continuous output power per channel into an 8-ohm load with a supply voltage range of 8.5 V to 18 V. The device features a total harmonic distortion plus noise (THD+N) of 0.025% and operates from -40°C to +85°C. Packaged in a 48-pin HTQFP, it accepts analog inputs and includes shutdown functionality.
Feature Summary
- Filter-free operation eliminates the need for external LC filters at the outputs.
- Integrated digital volume control allows adjustment across a wide dynamic range.
- High efficiency design reduces heat generation compared to linear amplifiers.
Applications
- Smart speakers
- Soundbars
- Compact audio systems
Procurement Notes
Verify the specific suffix 'R' indicates reel packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure thermal management strategies align with the specified operating temperature range for reliable long-term performance in enclosed designs.
Selection Notes
Select this component for applications requiring high-efficiency stereo amplification without external filtering complexity. Compare against the TPA3100D2 series if higher power output or different supply voltage ranges are required. Verify that the 48-pin HTQFP package fits within the available PCB real estate constraints.
Part Context
This part belongs to the TPA3004D2 family of audio power amplifiers. It shares the same core architecture as the TPA3004D2PHP but differs in packaging format. The device is designed for consumer electronics where space savings and thermal efficiency are critical design parameters.
Replacement Considerations
The TPA3004D2PHPG4 serves as a lead-free alternative within the same product family. Both parts share identical electrical characteristics and pinouts, allowing for direct substitution in existing designs while meeting specific regulatory requirements.
