TPA3121D2PWPR

Overview

The TPA3121D2PWPR is a stereo Class-D audio power amplifier manufactured by Texas Instruments. It operates on a single supply voltage ranging from 10 V to 26 V and delivers up to 15 W of continuous output power per channel into a 4-ohm load. The device features a fixed gain of 36 dB and supports analog input signals. It is housed in a 24-pin HTSSOP package with an operating temperature range spanning from -40°C to +85°C.

Feature Summary

• Class-D topology for high efficiency
• Integrated thermal and short-circuit protection
• Pop-suppression circuitry to reduce startup noise

Applications

• Portable media players
• Desktop speakers
• Home theater systems

Procurement Notes

Verify the specific suffix 'PWPR' indicates tape-and-reel packaging when sourcing components. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected distributor provides traceable data sheets matching the exact part number to avoid counterfeit risks.

Selection Notes

Select this component for designs requiring moderate stereo output power within a compact surface-mount footprint. The fixed 36 dB gain simplifies signal chain design by reducing external resistor requirements. Consider the 24-pin HTSSOP package constraints regarding thermal dissipation and PCB layout space during the initial schematic phase.

Part Context

This device belongs to the TPA3121D2 series, which includes variants such as the tube-packaged TPA3121D2PWP. The PWPR suffix specifically denotes the reel-based packaging format intended for automated assembly processes. All variants share identical electrical characteristics and pin configurations.

Replacement Considerations

The TPA3121D2PWP serves as a direct functional equivalent differing only in packaging format. Verify that any substitute maintains the same 24-pin HTSSOP outline dimensions and thermal pad specifications to ensure mechanical compatibility.
