Description and Introduction

4-Channel Automotive Digital Amplifiers 36-HSSOP -40 to 105 The TAS5414ATDKDQ1 is a 4-channel digital input automotive Class-D audio amplifier from Texas Instruments (TI). Here are the factual details from Ic-phoenix technical data files:

### **Manufacturer:**  
Texas Instruments (TI)  

### **Specifications:**  
- **Channels:** 4  
- **Output Power:** 21 W per channel (4 Ω, 10% THD+N at 14.4 V)  
- **Supply Voltage Range:** 4.5 V to 26.4 V  
- **Efficiency:** >90% (typical)  
- **THD+N:** <0.1% (1 W, 4 Ω)  
- **Signal-to-Noise Ratio (SNR):** 105 dB (A-weighted)  
- **Modulation Scheme:** PWM (Pulse Width Modulation)  
- **Input Interface:** I²S, TDM, or analog (with external ADC)  
- **Protection Features:** Overcurrent, overtemperature, undervoltage, and short-circuit protection  
- **Package:** 32-pin HTSSOP (PowerPAD™)  
- **Operating Temperature Range:** -40°C to +105°C  
- **AEC-Q100 Qualified:** Yes (Automotive Grade 1)  

### **Descriptions:**  
The TAS5414ATDKDQ1 is a high-efficiency Class-D amplifier designed for automotive audio systems. It supports digital audio input (I²S/TDM) and provides high-quality audio output with low distortion. It integrates protection mechanisms for reliable operation in harsh automotive environments.  

### **Features:**  
- **Digital Input:** Supports I²S and TDM formats (up to 8 channels).  
- **High Efficiency:** Reduces power dissipation and thermal requirements.  
- **Flexible Power Supply:** Operates from a single 12 V or 24 V automotive battery.  
- **Integrated Diagnostics:** Provides fault reporting for system monitoring.  
- **Small Footprint:** HTSSOP package with PowerPAD™ for thermal management.  
- **EMI Performance:** Optimized for reduced electromagnetic interference (EMI).  

This information is strictly based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

4-Channel Automotive Digital Amplifiers 36-HSSOP -40 to 105

Alternative Part Number

  • TAS5424ATDKDQ1 --: Same TAS54xx family 4-channel Class-D automotive amplifier in the same HTSSOP-44 (DKD) package, offering higher output power and a similar pinout, making it a strong drop-in upgrade candidate.
  • TAS5414BTDKDQ1 --: Updated 'B' revision of the same 4-channel automotive Class-D amplifier in the identical DKD package, with improved performance and the same control interface, so it is largely pin-compatible.
  • TDA7850 --: Widely used 4-channel Class-AB automotive audio amplifier with comparable supply voltage and output power class; requires board-level redesign but is a proven alternative for automotive head-unit audio stages.
  • TAS5414BTDKDRQ1 --: Same TAS5414 family Class-D audio amplifier in the same HTSSOP package with improved revision, pin-compatible and functionally equivalent for automotive audio applications.
