Overview
The TAS5424ATDKDQ1 is a four-channel automotive digital amplifier from Texas Instruments. It operates within an 8V to 22V supply voltage range and supports Class-D output topology. The device delivers up to 116W x 2 @ 2 ohms or 58W x 4 @ 4 ohms. It features a 44-BSSOP package with exposed pad, rated for -40°C to 105°C ambient temperature. Key specifications include AEC-Q100 qualification and support for differential inputs.
Feature Summary
- Four-channel digital amplification architecture designed for automotive audio systems
- Integrated protection mechanisms including thermal shutdown and short-circuit protection
- Supports I2C interface for configuration control and system management
Applications
- Automotive center console speaker systems
- Vehicle door panel audio deployment
- Rear seat entertainment audio channels
Procurement Notes
Verify the specific suffix (e.g., G4) against the target datasheet revision to ensure pinout and electrical parameter compatibility. Confirm that the 44-HSSOP package dimensions match the PCB footprint requirements. Check for any recent Product Change Notifications regarding assembly site or material composition changes before finalizing procurement.
Selection Notes
Select this component when a high-power, multi-channel solution is required for automotive environments. Ensure the design accommodates the 44-pin BSSOP package size and thermal dissipation needs. Verify that the host controller supports the necessary I2C communication protocol for amplifier configuration and status monitoring.
Part Context
This part belongs to the TAS54x4 family of four-channel automotive digital amplifiers. It shares functional similarities with the TAS5414 series but offers higher power output capabilities. The device is engineered to meet strict automotive reliability standards while providing efficient digital audio processing in a compact form factor.
Replacement Considerations
The TAS5424ATDKDRMQ1 is listed as obsolete with MFR recommended alternatives available. Verify if the TAS5424ATDKDQ1G4 variant serves as a direct drop-in replacement with identical functionality and packaging.
