TPA3008D2PHPRG4

Overview

The TPA3008D2PHPRG4 is a stereo Class-D audio power amplifier manufactured by Texas Instruments. It delivers 10 W of continuous output power into an 8-ohm load with less than 0.1% total harmonic distortion plus noise (THD+N) at a 26 V supply voltage. The device operates on a single power supply ranging from 5.5 V to 26 V and features a fixed gain of 36 dB. Packaged in a 48-pin HTQFP, it supports differential inputs and includes integrated protection mechanisms such as thermal shutdown and short-circuit protection.

Feature Summary

• Class-D architecture provides high efficiency for battery-powered applications
• Integrated thermal and short-circuit protection ensures operational reliability
• Fixed 36 dB gain simplifies system design and reduces external component count

Applications

• Portable media players and MP3 devices
• Bluetooth speakers and wireless audio systems
• Personal computers and all-in-one desktops
• LCD monitors and televisions

Procurement Notes

Verify the specific suffix 'RG4' indicates lead-free and RoHS compliance status according to the manufacturer's current documentation. Confirm the package type matches the required PCB footprint. Ensure the operating environment stays within the specified temperature range to maintain performance specifications.

Selection Notes

Select this component when a compact stereo solution is required for low-to-mid power audio applications. The fixed gain configuration eliminates the need for external volume control resistors. Consider the thermal requirements of the HTQFP package for proper heat dissipation in enclosed designs.

Part Context

This part belongs to the TPA300xD2 family of stereo Class-D amplifiers. It shares architectural similarities with the TPA3100D2 but offers lower output power suitable for smaller form factors. The device integrates gate drivers and output FETs into a single monolithic IC.

Replacement Considerations

The TPA3008D2PHPG4 is a direct pin-compatible alternative without the reel packaging suffix. For higher power requirements, the TPA3120D2 or TPA3121D2 may be considered, though layout changes might be necessary.
