Description and Introduction

2.75-W Mono Class-D Audio Amplifier with 2 V/V Fixed Gain (TPA2032) 9-DSBGA -40 to 85 The TPA2032D1YZFR is a Class-D audio amplifier manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Texas Instruments (TI)  
- **Package:** DSBGA (YZF), 9-bump, 1.56 mm x 1.56 mm  
- **Type:** Class-D Audio Amplifier  
- **Output Power:** 1.7 W into 4 Ω at 5 V (THD+N = 1%)  
- **Supply Voltage Range:** 2.5 V to 5.5 V  
- **Efficiency:** Up to 90%  
- **THD+N:** <0.3% (1 W, 4 Ω)  
- **SNR:** >95 dB (A-weighted)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Shutdown Current:** <1 µA  

### **Descriptions:**
The TPA2032D1YZFR is a mono, filter-free Class-D audio amplifier designed for portable applications. It features a low-power consumption design, making it suitable for battery-powered devices. The device integrates a feedback loop to improve PSRR and reduce noise.

### **Features:**
- **Filterless Operation:** Eliminates the need for external LC filters.  
- **Low Quiescent Current:** 2.3 mA (typical) for extended battery life.  
- **Pop & Click Suppression:** Minimizes audible noise during power-up/down.  
- **Thermal & Short-Circuit Protection:** Enhances reliability.  
- **Small Footprint:** Ultra-compact DSBGA package for space-constrained designs.  
- **I²C Control Interface:** Allows gain and shutdown control.
