Description and Introduction

Mono, Fully Differential, Class-AB Audio Amplifier The TPA6211A1DGN is a mono Class-D audio amplifier manufactured by Texas Instruments (TEXAS). Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Output Power:** 1.4W into 8Ω at 5V (THD+N = 10%)  
- **Supply Voltage Range:** 2.5V to 5.5V  
- **Efficiency:** Up to 90% (reduces power dissipation)  
- **THD+N (Total Harmonic Distortion + Noise):** 0.3% (typical at 1W, 8Ω, 5V)  
- **Quiescent Current:** 2.5mA (typical)  
- **Shutdown Current:** 0.01µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-Pin MSOP (DGN)  

### **Descriptions:**  
- The TPA6211A1DGN is a low-power, high-efficiency Class-D audio amplifier designed for portable applications.  
- It features a differential input to reduce noise and improve audio quality.  
- The device includes built-in thermal and short-circuit protection.  

### **Features:**  
- **Filterless Operation:** Eliminates the need for external LC output filters.  
- **Low Quiescent Current:** Enhances battery life in portable devices.  
- **Pop & Click Suppression:** Minimizes audible noise during power-up/down.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Short-Circuit Protection:** Safeguards the amplifier under fault conditions.  
- **Small Footprint:** Suitable for space-constrained applications.  

This information is strictly based on Texas Instruments' official documentation for the TPA6211A1DGN.

Application Scenarios & Design Considerations

Mono, Fully Differential, Class-AB Audio Amplifier

Alternative Part Number

  • LM4871MM --: Similar 1.1W audio power amplifier in MSOP package with comparable supply range and pinout, suitable drop-in for many designs.
  • PAM8302AAS --: 2.5W class-D audio amplifier in MSOP-8, higher output but electrically compatible for speaker drive applications.
  • MAX9710EUA --: 1.2W stereo audio amplifier in µMAX package, similar gain and supply requirements, usable as functional replacement.
