TAS5412TPHDRQ1

Overview

The TAS5412TPHDRQ1 is a two-channel Class-D audio amplifier designed for automotive applications, featuring analog single-ended inputs and I2C diagnostics. It delivers up to 79 W or 150 W of output power with a total harmonic distortion plus noise of 0.02%. The device operates on a single supply voltage ranging from 6 V to 24 V and supports load impedances of 4 Ohms. Key electrical parameters include a minimum operating temperature of -40°C and a maximum of +105°C. It offers configurable gain settings of 12 dB, 20 dB, 26 dB, or 32 dB, with an operating supply current of 125 mA. The component is housed in a 64-pin HTQFP package and meets AEC-Q100 qualification standards.

Feature Summary

• Includes built-in I2C diagnostic capabilities for system monitoring and fault detection.
• Supports multiple programmable gain configurations to adapt to various input signal levels.

Applications

• Automotive infotainment systems
• Vehicle speaker amplification modules
• High-fidelity car audio subwoofers

Procurement Notes

Verify the specific suffix and revision level against the manufacturer's latest datasheet to ensure compatibility with your design requirements. Confirm that the HTQFP-64 package dimensions align with your PCB footprint specifications. Ensure that the thermal management solution accounts for the maximum operating temperature of +105°C under full load conditions. Check for any recent product change notifications regarding pinout or electrical characteristics before finalizing procurement orders.

Selection Notes

Select this component when a robust, automotive-grade Class-D amplifier with integrated diagnostics is required. It is suitable for designs needing high output power in a compact form factor. Consider the available gain options to match the source impedance and desired volume levels. Ensure the power supply rail can support the 6 V to 24 V operating range and provide sufficient current for peak audio demands without exceeding thermal limits.

Part Context

This part belongs to the Texas Instruments TAS5412 family of auto digital amplifiers. It is specifically engineered for automotive environments, meeting stringent reliability standards such as AEC-Q100. The device complements other TI audio solutions by providing a complete amplification stage with advanced control features. It is often used in conjunction with evaluation modules like the TAS5412Q1PHDEVM for development and testing purposes.

Replacement Considerations

Check for direct pin-to-pin replacements within the same family, such as variants with different gain settings or packaging options. Verify if newer revisions of the TAS5412 series offer improved performance or updated features. Ensure that any substitute component maintains the same AEC-Q100 qualification and thermal characteristics to avoid redesigning the thermal management system.
