TPA3008D2PHPR

Overview

The TPA3008D2PHPR is a 10-W per channel stereo Class-D audio power amplifier manufactured by Texas Instruments. It operates on a single supply voltage ranging from 8.5 V to 18 V and supports load impedances of 8 Ω or 16 Ω. The device achieves up to 92% efficiency, eliminating the need for external heatsinks during music playback. It features four selectable fixed gain settings: 15.3 dB, 21.2 dB, 27.2 dB, and 31.8 dB. The amplifier utilizes differential inputs to minimize common-mode noise and includes thermal protection with automatic recovery. It is housed in a 48-pin HTQFP PowerPAD™ package with an operating temperature range of -40°C to 85°C.

Feature Summary

• High-efficiency Class-D operation eliminates the requirement for external heatsinks
• Differential input design minimizes common-mode noise interference
• Integrated thermal and short-circuit protection with automatic recovery capability

Applications

• LCD monitors and televisions
• All-In-One personal computers

Procurement Notes

Verify the specific suffix 'PHPR' corresponds to the reel packaging configuration as defined in the official datasheet. Confirm that the application circuit matches the required gain setting selected via the hardware pins. Ensure the PCB layout adheres to the recommended thermal pad connection guidelines for the HTQFP-48 package to maintain optimal heat dissipation performance.

Selection Notes

Select this component when a high-efficiency stereo amplifier is required for space-constrained consumer electronics. It is suitable for designs utilizing 8.5 V to 18 V single-supply systems. Consider this part if differential signaling is preferred to reduce noise. Verify that the target application does not require variable gain control, as this model offers only fixed gain options.

Part Context

This device belongs to the TPA3008D2 family of efficient Class-D audio amplifiers. It shares pinout compatibility with the TPA3000D series, facilitating potential design upgrades. The PowerPAD™ technology provides a thermally enhanced solution within a compact form factor, addressing the thermal management challenges typical of high-power audio applications in small enclosures.

Replacement Considerations

Check for direct pin-compatible alternatives within the TPA3000D family if different gain configurations are needed. Verify that any substitute maintains the same 48-pin HTQFP PowerPAD™ footprint and supports the required 8.5 V to 18 V supply range.
