Description and Introduction

80-mW DirectPath(TM) Stereo Headphone Amplifier 16-DSBGA -40 to 85 The TPA4411YZHR is a mono, 1.4W audio power amplifier manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Output Power:** 1.4W into 8Ω at 5V (THD+N = 10%)  
- **Supply Voltage Range:** 2.5V to 5.5V  
- **Quiescent Current:** 2.3mA (typical)  
- **Shutdown Current:** 0.1µA (typical)  
- **Total Harmonic Distortion + Noise (THD+N):** 0.2% (1kHz, 1W into 8Ω)  
- **Signal-to-Noise Ratio (SNR):** 95dB (A-weighted)  
- **Gain:** Fixed at 6dB  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 9-pin DSBGA (YZH)  

### **Descriptions:**
- The TPA4411YZHR is a Class-AB audio amplifier designed for portable applications.  
- It features a low-power shutdown mode for power-saving operation.  
- The device includes an internal depop circuit to reduce turn-on/off transients.  
- It is optimized for driving small speakers in battery-powered systems.  

### **Features:**
- **Low Quiescent Current:** Enhances battery life in portable devices.  
- **Thermal and Short-Circuit Protection:** Improves reliability.  
- **Small Form Factor:** 9-pin DSBGA package saves PCB space.  
- **Improved PSRR (Power Supply Rejection Ratio):** Reduces noise from supply variations.  
- **No External Coupling Capacitors Required:** Simplifies design and reduces BOM cost.  

This information is strictly factual from the TI datasheet and does not include any additional guidance or recommendations.
