TAS5414BTPHDRQ1

Overview

The TAS5414BTPHDRQ1 is a four-channel Class-D automotive audio amplifier manufactured by Texas Instruments. It delivers 150 W of output power with a total harmonic distortion plus noise of 0.02%. The device operates on a supply voltage range from 6 V to 24 V and supports a minimum load impedance of 2 Ohms. It features analog input, utilizes an HTQFP-64 package, and functions within a temperature range of -40°C to +105°C. The component holds AEC-Q100 qualification for automotive reliability.

Feature Summary

• Four-channel quad architecture designed for high-power automotive audio applications
• Class-D topology providing high efficiency and reduced thermal generation compared to linear amplifiers
• AEC-Q100 qualified for robust operation in demanding automotive environments

Applications

• Automotive center console speaker systems
• Rear seat entertainment audio channels
• High-fidelity multi-zone vehicle sound reinforcement

Procurement Notes

Verify the specific suffix 'HDRQ1' against official Texas Instruments documentation to confirm the tape-and-reel packaging configuration. Ensure compatibility with the target PCB footprint for the HTQFP-64 package. Confirm that the design accounts for the specified 6 V to 24 V operating voltage range and thermal requirements for the intended application environment.

Selection Notes

Select this component when designing systems requiring four independent high-power channels with low distortion. It is suitable for replacing legacy Class-A/B solutions where size and heat reduction are critical. Verify that the system can support the required 2 Ohm load impedance per channel to achieve the rated 150 W output performance.

Part Context

This part belongs to the TAS5414B series, which represents Texas Instruments' digital amplifier solutions for the automotive market. These amplifiers enable cost-effective eight-channel audio systems by combining multiple units or utilizing their high channel count. They offer significant advantages in weight, size, and power efficiency over traditional linear amplifier architectures.

Replacement Considerations

TAS5414ATPHDRMQ1: Lower power variant (90 W) with different voltage limits. TAS5414CTPHDR: Non-automotive grade with lower power output.
