- **Gain:** Fixed at 6 dB (2 V/V)  
- **Operating Temperature Range:** -40°C to 85°C  

### **Descriptions:**  
The TPA731D is a mono, fully differential audio power amplifier designed for portable applications. It features a low-power shutdown mode and operates from a single supply. The device includes an internal depop circuit to reduce audible noise during power-up and shutdown.  

### **Features:**  
- Fully differential design reduces RF rectification  
- No output coupling capacitors required  
- Internal depop circuitry  
- Thermal and short-circuit protection  
- Unity-gain stable  
- Available in an 8-pin SOIC (D) package
