TPA1517NE

Overview

The TPA1517NE is a Texas Instruments stereo audio amplifier in a 20-pin PDIP package. It delivers 6W output into an 8-ohm load with 0.1% THD+N. Operating on a single supply from 9.5V to 18V, it features Class-AB topology and 20dB gain. The device draws 45mA quiescent current and supports 4A output current across a -40°C to +85°C range.

Feature Summary

• Delivers high-fidelity stereo audio amplification with low distortion characteristics
• Operates efficiently on a single power supply rail for simplified circuit design
• Provides robust output drive capability suitable for direct speaker connection

Applications

• High-power stereo speaker systems
• Professional audio equipment
• Home theater receivers

Procurement Notes

Verify the specific package type matches your PCB footprint requirements. Confirm that the single-supply voltage range aligns with your system's power delivery capabilities. Ensure thermal management solutions are adequate for the expected operating conditions and output power levels.

Selection Notes

Select this component when a through-hole stereo amplifier with high output power is required. Consider the 20-pin DIP package for prototyping or legacy board designs. Evaluate the single-supply operation against available power rails in the target application environment.

Part Context

This part belongs to the TPA1517 series of audio amplifiers manufactured by Texas Instruments. It is categorized under audio ICs and specifically designed for stereo applications requiring significant power output. The series includes variants with different packaging options to suit various manufacturing needs.

Replacement Considerations

The TPA1517DWPR serves as a surface-mount alternative within the same family. Verify pin compatibility and thermal performance differences between the PDIP and HSOP packages before substitution.
