TAS5424ATDKDRQ1G4

Overview

The TAS5424ATDKDRQ1G4 is a four-channel automotive digital amplifier manufactured by Texas Instruments. It operates within a supply voltage range of 8V to 22V and supports an operating temperature from -40°C to 105°C. The device delivers up to 116W x 2 at 2 ohms or 58W x 4 at 4 ohms. It utilizes a 44-HSSOP package with exposed pad for thermal management.

Feature Summary

• Four-channel Class-D audio amplification architecture
• Integrated I2C control interface for configuration
• Automotive-grade reliability with AEC-Q100 qualification
• Built-in protection mechanisms including thermal and short-circuit safeguards

Applications

• Automotive infotainment systems
• Vehicle speaker array integration
• Digital audio processing units in cars

Procurement Notes

Verify the exact suffix 'R' indicates tape-and-reel packaging versus 'D' for cut tape. Confirm current production status as some variants are obsolete. Ensure compatibility with existing PCB footprints for the 44-HSSOP package. Check for RoHS3 compliance requirements specific to your region.

Selection Notes

Select this component when high-power multi-channel output is required in automotive environments. Consider the 44-HSSOP package size constraints. Evaluate thermal dissipation needs given the high power output capabilities. Verify I2C bus compatibility with the host controller.

Part Context

This part belongs to the TAS54xA series of four-channel automotive digital amplifiers. It shares functional similarities with the TAS5414A but differs in package type and specific pinout configurations. The series is designed for robust performance in demanding vehicle electrical environments.

Replacement Considerations

Check for direct substitutes like TAS5424ATDKDQ1G4 if reel quantity is not required. Verify pin-to-pin compatibility before replacing older obsolete versions such as TAS5424ATDKDRMQ1.
