TAS5414ATDKDRQ1

Overview

The TAS5414ATDKDRQ1 is a four-channel automotive digital amplifier from Texas Instruments, designed for high-performance audio applications. It operates as a Class-D amplifier with a fixed gain of 32 dB and supports single-ended input configurations. The device delivers up to 90 W of output power into a 2-ohm load, maintaining a total harmonic distortion plus noise (THD+N) of 0.02%. It functions within a supply voltage range of 8 V to 22 V and draws operating currents of 80 mA or 240 mA depending on the mode. The component is housed in a 36-pin HSSOP package and is qualified under AEC-Q100 standards for automotive reliability.

Feature Summary

• Four-channel digital amplification architecture optimized for automotive environments
• Integrated clip-detection circuitry for BTL Class D operation
• AEC-Q100 qualification ensuring robustness for vehicle electronics

Applications

• Automotive speaker systems requiring multi-channel digital control
• Bridge-tied-load (BTL) amplifier implementations
• High-fidelity car audio processing units

Procurement Notes

Verify the specific suffix 'DKDR' against the official datasheet to confirm pinout and packaging details, as variations exist within the TAS5414 family. Confirm current lifecycle status, as some variants are marked as Not Recommended for New Designs (NRND). Ensure compatibility with existing PCB footprints for the 36-pin HSSOP package before finalizing procurement decisions.

Selection Notes

Select this component when a four-channel digital interface is required for automotive audio systems. It is suitable for designs needing integrated clip detection and high power density in a compact form factor. Consider the 32 dB fixed gain and 2-ohm load capability during system impedance matching. Verify that the 8 V to 22 V supply range aligns with the vehicle's electrical architecture.
