TPA3100D2IRGZRQ1

Overview

The TPA3100D2IRGZRQ1 is an automotive catalog stereo Class-D audio power amplifier manufactured by Texas Instruments. It delivers 20 watts of output power and operates within a supply voltage range of 10 V to 26 V. The device features two channels with a gain of 36 dB and supports an 8-ohm load impedance. It utilizes a 48-pin HVQCCN package (VQFN) measuring 7 mm by 7 mm. The operational temperature range spans from -40 °C to +85 °C, ensuring reliability in automotive environments.

Feature Summary

• Automotive-grade design compliant with AEC-Q100 standards for enhanced durability
• Class-D topology providing high efficiency and reduced thermal management requirements
• Integrated protection mechanisms including short-circuit and thermal shutdown

Applications

• In-car infotainment systems
• Vehicle door speaker integration
• Center console audio modules

Procurement Notes

Verify the specific suffix 'Q1' confirms automotive qualification status. Ensure the 48-VQFN package dimensions match the target PCB footprint. Confirm RoHS compliance and lead-free status align with regional manufacturing regulations. Validate that the operating temperature range meets the specific environmental constraints of the intended installation location.

Selection Notes

Select this component when automotive certification is mandatory for audio applications. The 20-watt stereo output suits standard vehicle speaker configurations. Consider the 48-pin VQFN package for compact board layouts requiring efficient heat dissipation through the exposed pad. Verify compatibility with the system's 10 V to 26 V power supply architecture.

Part Context

This part belongs to the TPA3100D2 series of Class-D amplifiers. The 'Q1' suffix denotes automotive grade qualification, distinguishing it from commercial variants like the TPA3100D2RGZR. It shares core functionality with other members of the family but adheres to stricter automotive reliability standards.

Replacement Considerations

Direct substitutes include the TPA3100D2RGZR for non-automotive use or the TPA3101D2RGZR for lower power requirements. Verify pinout compatibility and package dimensions before swapping components.
