TAS5414CTPHDRQ1

Overview

The TAS5414CTPHDRQ1 is a four-channel Class-D audio amplifier designed for automotive applications, featuring AEC-Q100 qualification. It operates within a supply voltage range of 6 V to 24 V and supports a minimum load impedance of 4 Ohms. The device delivers 23 W of output power with a total harmonic distortion plus noise (THD+N) of 0.02%. It utilizes a single-ended input configuration and provides a fixed gain of 32 dB. The amplifier is housed in an HTQFP-64 package suitable for surface-mount installation and functions reliably across an operating temperature range from -40°C to +105°C.

Feature Summary

• Four-channel stereo Class-D architecture optimized for automotive audio systems
• AEC-Q100 qualified for robust performance in vehicle environments
• Single-ended input interface simplifies system integration
• High efficiency operation reduces thermal management requirements

Applications

• Automotive center console speaker amplification
• Vehicle door panel audio driver circuits
• Rear seat entertainment system audio outputs
• Multi-zone car audio distribution networks

Procurement Notes

Verify the specific suffix 'Q1' indicates automotive grade qualification distinct from commercial variants. Confirm the HTQFP-64 package outline matches your PCB footprint design. Ensure the 4-Ohm load specification aligns with your speaker impedance requirements. Check for any recent lifecycle status updates regarding new design recommendations.

Selection Notes

Select this component when a four-channel solution is required for 4-Ohm loads in automotive settings. Compare against the TAS5414ATPHDRMQ1 if higher power output or 2-Ohm compatibility is needed. Consider the 6V minimum supply voltage constraint for low-voltage vehicle architectures. Evaluate thermal dissipation needs based on the 23W per channel rating at 4 Ohms.

Part Context

This part belongs to the Texas Instruments TAS5414 family of digital audio amplifiers. These devices are engineered to replace traditional Class-A/B amplifiers in vehicles, offering reduced size and weight while maintaining high audio fidelity. The family includes variants tailored for different power levels and load impedances to support scalable automotive audio designs.

Replacement Considerations

The TAS5414ATPHDRMQ1 serves as a higher-power alternative within the same family. Verify pin-to-pin compatibility before substitution. Ensure the replacement variant meets the specific voltage and load requirements of the existing circuit design.
