Overview
The TAS5414ATPHDRMQ1 is a four-channel automotive digital Class-D audio amplifier manufactured by Texas Instruments. It operates within a supply voltage range of 8 V to 22 V and supports output configurations including mono, stereo, and quad setups. The device delivers up to 90 W of output power into a 2-ohm load with a total harmonic distortion plus noise of 0.02%. It features a fixed gain of 32 dB and an input current ranging from 80 mA to 240 mA. The component is housed in an HTQFP-64 package and is qualified under AEC-Q100 standards for operation between -40°C and +105°C.
Feature Summary
- Supports multiple channel configurations including single-channel mono, two-channel stereo, and four-channel stereo outputs.
Applications
- Automotive audio systems requiring high-power multi-channel amplification
Procurement Notes
Verify the specific suffix 'MQ1' against official Texas Instruments documentation to confirm automotive qualification status and exact pinout compatibility. Ensure that the HTQFP-64 package dimensions match the target PCB footprint requirements. Confirm that the 8V to 22V supply range aligns with the vehicle's electrical architecture before finalizing procurement decisions.
Selection Notes
Select this component when designing automotive audio applications requiring a four-channel Class-D solution with digital control interfaces. The AEC-Q100 qualification ensures reliability in harsh automotive environments. Consider the 90W power capability and 2-ohm load support for driving low-impedance speakers efficiently while maintaining high fidelity performance.
Part Context
This part belongs to the TAS5414A series of automotive digital amplifiers. It is designed specifically for high-performance audio applications in vehicles. The series offers various packaging options and channel configurations to suit different system architectures. The MQ1 suffix indicates specific automotive-grade manufacturing and testing protocols.
Replacement Considerations
Check for TAS5414CTPHDQ1 or other TAS5414 variants with compatible packages. Verify if alternative parts meet the same AEC-Q100 and power output specifications.
