Overview
The TPA0142PWP is a stereo audio power amplifier manufactured by Texas Instruments, housed in a 24-pin HTSSOP package with an exposed pad. It operates on a single supply voltage ranging from 4.5 V to 5.5 V. The device delivers 2 W of continuous output power per channel into a 3-ohm load at 5 V supply with 10% THD+N. It integrates DC volume control functionality and features low quiescent current for battery-powered applications.
Feature Summary
- Integrates DC volume control circuitry for direct microprocessor interface
- Delivers high-efficiency stereo audio amplification in a compact surface-mount package
- Operates efficiently on a single low-voltage supply suitable for portable devices
Applications
- Portable multimedia players
- Mobile phones and smartphones
- Personal digital assistants (PDAs)
- MP3 players and audio modules
Procurement Notes
Verify component status as the TPA0142PWP is listed as obsolete or not recommended for new designs by the manufacturer. Confirm availability through authorized distributors or secondary markets. Ensure compatibility with existing PCB footprints if replacing legacy units. Check for moisture sensitivity levels and storage conditions prior to assembly.
Selection Notes
Select this component only for maintenance or replacement of existing designs where the specific pinout and integrated volume control are required. Evaluate alternative active devices from the same manufacturer family if new production is planned. Consider thermal performance within the HTSSOP-24 package when designing heat dissipation paths for the exposed pad.
Part Context
This part belongs to the TPA0142 series of audio amplifiers designed for low-voltage consumer electronics. It is distinct from higher-power Class-D amplifiers like the TPA3144 series due to its Class-AB topology and lower power output capabilities. The device focuses on simplicity and integration rather than maximum efficiency or power handling.
Replacement Considerations
Official substitutes include the TPA0142PWPR (tape and reel version) or compatible stereo amplifiers with similar voltage ranges and pinouts. Verify that replacement parts maintain the same volume control interface requirements.
