TPA1517DWP

Overview

The TPA1517DWP is a stereo audio power amplifier manufactured by Texas Instruments, housed in a 20-HSOP package. It operates as a Class-AB amplifier with a fixed gain of 20 dB and supports analog input signals. The device delivers 6 W of output power into an 8 Ohm load, utilizing a single power supply ranging from 9.5 V to 18 V. Key electrical specifications include a total harmonic distortion plus noise of 0.1%, a quiescent current of 45 mA, and a peak output current of 4 A. It functions within a temperature range of -40°C to +85°C.

Feature Summary

• Delivers high-fidelity stereo audio amplification using Class-AB topology for low distortion performance.
• Integrates built-in thermal protection mechanisms to safeguard the device during operation.
• Supports direct connection to speakers without requiring external coupling capacitors.

Applications

• High-power speaker systems
• Professional audio equipment
• Home theater setups

Procurement Notes

Verify the specific package variant, as the TPA1517 series includes both HSOP and PDIP options. Confirm that the application requires a single-supply configuration compatible with the 9.5 V to 18 V operating range. Ensure thermal management solutions are adequate for the expected power dissipation levels in the final design.

Selection Notes

Select this component when a robust Class-AB solution is required for driving 8 Ohm loads at high power levels. It is suitable for designs needing integrated thermal protection and fixed gain amplification. Consider alternative packages if surface-mount constraints differ from the HSOP-20 form factor.

Part Context

This part belongs to the TPA1517 family of stereo audio power amplifiers from Texas Instruments. The family provides various packaging options, including the through-hole TPA1517NE and the tape-and-reel TPA1517DWPR, all sharing identical core electrical characteristics and functionality.

Replacement Considerations

TPA1517DWPG4 is a verified lead-free replacement within the same product family.
