TPA2017D2RTJR

Overview

The TPA2017D2RTJR is a stereo, filter-free Class-D audio power amplifier manufactured by Texas Instruments. It delivers 2.8 watts per channel into an 8-ohm load with a single 5-volt supply. The device integrates Easy SmartGain technology for automatic gain control and dynamic range compression. It operates within a temperature range of -40°C to +85°C and utilizes a 20-pin WQFN package with an exposed pad for thermal management.

Feature Summary

• Integrates Easy SmartGain technology for automatic gain control and dynamic range compression
• Filter-free Class-D architecture eliminates the need for output filters
• Stereo configuration provides two independent audio channels

Applications

• Portable multimedia speakers
• Desktop computer speakers
• Home theater systems

Procurement Notes

Verify the specific suffix RTJR against the official datasheet to confirm tape-and-reel packaging and quantity. Ensure compatibility with the required operating voltage and thermal design constraints. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status if required for your assembly process.

Selection Notes

Select this component when a compact stereo solution with integrated gain control is required. It is suitable for applications where output filtering space is limited due to its filter-free design. Consider the 2.8W per channel output power relative to the speaker impedance and supply voltage available in the target system.

Part Context

This part belongs to the TPA2017D2 series from Texas Instruments. It is designed as a high-efficiency audio amplifier for consumer electronics. The series emphasizes ease of use through integrated smart gain features, reducing the complexity of external component selection for designers implementing stereo audio systems.

Replacement Considerations

Consult the official datasheet for direct pin-to-pin compatible alternatives within the same family. Verify that any substitute maintains the same output power rating and package dimensions. Ensure the replacement supports the required Easy SmartGain functionality if automatic gain control is critical to the application.
