Description and Introduction

Stereo, Class-AB Audio Amplifier with Volume Control and Stereo Headphone Drive The TPA6011A4PWPR is a Class-D stereo audio power amplifier manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Output Power:**  
  - 1.4 W per channel into 8 Ω at 5 V (THD+N = 10%)  
  - 2.3 W per channel into 4 Ω at 5 V (THD+N = 10%)  
- **Supply Voltage Range:** 2.5 V to 5.5 V  
- **Efficiency:** Up to 90% (Class-D operation)  
- **THD+N:** < 0.1% (1 W into 8 Ω, 5 V)  
- **Signal-to-Noise Ratio (SNR):** > 95 dB  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 24-pin HTSSOP (PW) with PowerPAD™  

### **Descriptions:**  
- The TPA6011A4PWPR is a stereo Class-D amplifier designed for portable audio applications.  
- It integrates a modulation scheme to reduce EMI and improve efficiency.  
- Features a shutdown mode for power savings when not in use.  
- Includes built-in thermal and short-circuit protection.  

### **Features:**  
- **Class-D Operation:** High efficiency with low power dissipation.  
- **Fixed Gain (6 dB):** Simplifies design by eliminating external gain-setting resistors.  
- **Pop & Click Suppression:** Minimizes audible noise during power-up/down.  
- **Low Quiescent Current:** 4 mA typical (5 V supply).  
- **Differential Inputs:** Reduces common-mode noise.  
- **Thermal & Short-Circuit Protection:** Enhances reliability.  
- **Small Footprint:** 24-pin HTSSOP package with PowerPAD for thermal management.
