TAS5414ATDKDMQ1G4

Overview

The TAS5414ATDKDMQ1G4 is a four-channel automotive digital Class-D audio amplifier manufactured by Texas Instruments. It operates within a supply voltage range of 6 V to 24 V and supports load impedances of 2 Ohms or 4 Ohms. The device delivers up to 90 W of output power with a total harmonic distortion plus noise (THD+N) of 0.02%. It features a fixed gain of 32 dB and an output current capability of 13.5 A. The component is housed in a 36-pin HSSOP package and is qualified under AEC-Q100 standards for operation between -40°C and +105°C.

Feature Summary

• Four-channel digital amplification architecture designed for automotive environments
• Integrated cycle-by-cycle current limiting circuit for pulse protection
• Supports single-ended analog input configurations
• Qualified for high-temperature automotive applications

Applications

• Automotive center console speaker systems
• Vehicle door panel audio outputs
• Rear seat entertainment audio channels
• Multi-zone car audio distribution networks

Procurement Notes

Verify the specific suffix G4 indicates lead-free compliance and RoHS adherence before procurement. Confirm the HTQFP or HSSOP package variant matches the target PCB footprint, as pinouts may differ across TAS5414 series revisions. Ensure the design accounts for the specified thermal dissipation requirements given the 90 W power rating and operating temperature limits defined in the official datasheet.

Selection Notes

Select this component when a quad-channel solution is required for direct digital control interfaces in vehicles. Compare against TAS5414A variants if different packaging or specific automotive qualification levels are needed. Evaluate the 32 dB fixed gain against system headroom requirements. Consider the 36-pin HSSOP form factor for space-constrained dashboard or trunk installations where four independent channels are necessary.

Part Context

This part belongs to the TAS5414 family of automotive digital amplifiers from Texas Instruments. It shares functional similarities with the TAS5414ATPHDMQ1 but utilizes a distinct 36-pin HSSOP package instead of the HTQFP-64. The family is characterized by high-efficiency Class-D topology and robust protection features tailored for harsh automotive electrical environments.

Replacement Considerations

The TAS5414ATDKDQ1 is a non-G4 variant of the same base device. Verify if the absence of the G4 suffix affects lead-free status or RoHS compliance for specific regional regulations. Package compatibility must be confirmed as both share the 36-HSSOP outline.
