Description and Introduction

8 Channel Digital Audio PWM Processor The TAS5121 is a digital audio amplifier from Texas Instruments (TI). Here are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Power:** Up to 15W per channel (stereo) into 4Ω at 10% THD+N.
- **Supply Voltage Range:** 10V to 26V.
- **Modulation Scheme:** Advanced Digital Pulse Width Modulation (ADPWM).
- **Efficiency:** Up to 90%.
- **Signal-to-Noise Ratio (SNR):** >100dB (A-weighted).
- **Total Harmonic Distortion + Noise (THD+N):** <0.1% (typical).
- **Sampling Rate:** Supports up to 48kHz.
- **Operating Temperature Range:** -40°C to +85°C.
- **Package:** 32-pin HTSSOP (PowerPAD™).

### **Descriptions:**
- The TAS5121 is a high-efficiency, stereo Class-D audio amplifier designed for consumer audio applications.
- It integrates a digital PWM modulator and high-power MOSFET output stage.
- Features built-in protection circuits for overcurrent, overtemperature, and undervoltage conditions.
- Operates in a bridge-tied load (BTL) configuration.

### **Features:**
- **Digital Input:** Accepts I²S or left-justified audio data formats.
- **Low EMI:** Spread-spectrum modulation reduces electromagnetic interference.
- **Pop-Free Start-Up:** Minimizes audible artifacts during power-up.
- **Thermal and Short-Circuit Protection:** Enhances reliability.
- **Small Footprint:** Suitable for space-constrained designs.
