- **Shutdown Current:** <1 µA  
- **Operating Temperature Range:** -40°C to 85°C  

### **Descriptions:**  
The TPA0252PWP is a stereo Class-D audio amplifier designed for portable applications such as smartphones, tablets, and portable media players. It integrates a high-efficiency Class-D architecture, reducing power consumption while delivering clear audio output. The PowerPAD™ package enhances thermal performance, making it suitable for space-constrained designs.  

### **Features:**  
- **Stereo Class-D Amplifier:** Provides two-channel audio output.  
- **Low Supply Voltage Operation:** Works efficiently from 2.5 V to 5.5 V.  
- **High Efficiency:** Minimizes power loss, extending battery life.  
- **Thermal Protection:** Prevents overheating.  
- **Short-Circuit Protection:** Safeguards the amplifier from damage.  
- **Low Shutdown Current:** Reduces power consumption when inactive.  
- **Pop & Click Suppression:** Minimizes audible noise during power-up/down.  
- **Small Footprint:** HTSSOP package with PowerPAD™ for improved heat dissipation.

Application Scenarios & Design Considerations

Stereo Class-AB Audio Amplifier with Stereo Headphone Drive, Volume Control Memory

Alternative Part Number

  • MAX9710ETP+ --: Stereo 2.6W Class-AB audio amplifier in a 20-pin TQFN package, functionally similar to the TPA0252 and usable as a drop-in style replacement with minor layout adjustments.
  • LM4950TA --: Dual 3.1W audio power amplifier from TI's Boomer family, same manufacturer and similar output power/class, offering an easy second-source option within the same vendor ecosystem.
  • PAM8403 --: Low-cost 3W stereo Class-D audio amplifier in a small package, suitable for similar audio output applications where a Class-D alternative is acceptable.
  • LM4871MX/NOPB --: Similar mono class-AB audio power amplifier in a comparable power range, widely available and pin-compatible in function for many TPA0252 applications.
  • PAM8403DR --: Low-cost class-D stereo audio amplifier with comparable output power and supply voltage, usable as a functional alternative where efficiency matters.
