TPA3116D2QDADRQ1

Overview

The TPA3116D2QDADRQ1 is a stereo Class-D audio amplifier power stage designed for automotive applications. It delivers up to 50W per channel into a 4-ohm load with a total harmonic distortion plus noise of 0.1%. The device operates on a supply voltage ranging from 4.5V to 26V and features an analog input interface. It is housed in a 32-pin HTSSOP package and meets AEC-Q100 qualification standards, ensuring reliability within an operating temperature range of -40°C to +125°C.

Feature Summary

• Automotive-grade Class-D architecture optimized for high efficiency and low idle loss
• Integrated SpeakerGuard protection against overvoltage, undervoltage, thermal stress, DC offset, and short circuits
• Supports multiple switching frequencies to mitigate AM radio interference
• Enables master-slave synchronization for multi-channel system expansion

Applications

• Automotive center stack audio amplifiers
• Door module integrated audio systems
• High-fidelity car speaker drivers
• Multi-zone vehicle sound reinforcement

Procurement Notes

Verify the suffix QDADRQ1 confirms the specific tape-and-reel packaging configuration and automotive grade designation. Ensure the component matches the 32-HTSSOP footprint requirements for your PCB layout. Confirm that the AEC-Q100 qualification aligns with your vehicle's environmental stress specifications before finalizing procurement orders.

Selection Notes

Select this component when designing for strict automotive thermal and electrical environments requiring robust protection mechanisms. It is suitable for applications needing high output power without external heat sinks under typical conditions. Consider the 32-pin package size if space constraints are critical. Verify compatibility with existing analog audio source interfaces and gain settings.

Part Context

This part belongs to the TPA311xD2-Q1 series of stereo efficient digital amplifier power stages. It shares architectural similarities with other members like the TPA3118D2-Q1 but offers specific power ratings suited for standard automotive speaker loads. The series is characterized by its ability to drive speakers efficiently while maintaining high audio fidelity.

Replacement Considerations

The non-automotive TPA3116D2DAD serves as a functional equivalent but lacks AEC-Q100 certification and has a different operating temperature range. Substitution requires verifying that the lower temperature rating does not compromise automotive reliability standards.
