Overview
The TPA2001D2PWPR is a third-generation, 5-V Class-D stereo audio power amplifier manufactured by Texas Instruments. It delivers 1 W of continuous output power into an 8-ohm load with a total harmonic distortion plus noise (THD+N) of 0.3%. The device operates within a supply voltage range of 2.7 V to 5.5 V and supports analog input signals. It features a fixed gain of 20 dB and includes thermal shutdown protection. The component is housed in a 24-pin HTSSOP package with an exposed pad for thermal management.
Feature Summary
- Filterless Class-D architecture eliminates the need for external output filters, reducing component count and board space.
- Third-generation design improvements provide enhanced efficiency and lower quiescent current compared to previous iterations.
- Integrated thermal shutdown protection safeguards the device during overtemperature conditions.
Applications
- Portable multimedia devices requiring high-efficiency audio amplification
- Small form-factor stereo speaker systems
- Battery-powered consumer electronics
Procurement Notes
Verify the specific suffix 'PWPR' corresponds to the 24-HTSSOP package with tape-and-reel packaging configuration. Confirm RoHS compliance status through the official datasheet or manufacturer documentation before integration. Ensure ESD handling protocols are followed due to moisture sensitivity classification.
Selection Notes
Select this component for applications requiring a compact, low-voltage stereo amplifier solution. It is suitable where filterless operation simplifies the bill of materials. Consider the 24-pin package size and thermal requirements when designing the PCB layout for adequate heat dissipation.
