TAS5717LPHPR

Overview

The TAS5717LPHPR is a digital audio power amplifier manufactured by Texas Instruments, belonging to the TAS5717 series. It features a Class-D architecture with integrated cap-free headphone amplification capabilities. The device supports stereo output and operates within a supply voltage range of 3 V to 3.6 V. Key electrical specifications include a maximum output power of 15 W and a total harmonic distortion plus noise (THD+N) of 0.13%. It is designed for an 8 Ohm load impedance and functions within a temperature range of 0°C to +85°C. The component is housed in a 48-pin HTQFP package.

Feature Summary

• Integrates a cap-free headphone amplifier alongside the main digital audio power stage
• Supports digital audio input interfaces including I2S for direct connection to digital sources
• Includes built-in protection mechanisms such as thermal shutdown and short-circuit protection

Applications

• Portable consumer electronics requiring high-efficiency audio amplification
• Digital audio systems utilizing I2S interface connectivity
• Devices integrating both speaker and headphone output stages

Procurement Notes

Verify the specific suffix 'L' against official Texas Instruments documentation to confirm pinout or functional variations compared to the standard TAS5717PHPR. Ensure compatibility with the required 3V to 3.6V supply rails and confirm the HTQFP-48 package availability through authorized distributors. Cross-reference the datasheet revision date to ensure alignment with current manufacturing standards.

Selection Notes

Select this component when a low-voltage digital amplifier with integrated headphone drive is required. The 15W output capability suits applications needing robust performance from limited power supplies. Consider the HTQFP-48 package size for PCB layout constraints. Verify that the system design accommodates the specified 0°C to +85°C operating temperature range and 8 Ohm load requirements.

Part Context

The TAS5717LPHPR is part of the Texas Instruments TAS5717 family of digital audio power amplifiers. This series is characterized by its ability to deliver high power efficiency while maintaining audio fidelity. The inclusion of an integrated headphone amplifier distinguishes it from basic power-only variants, offering a consolidated solution for multi-output audio devices.

Replacement Considerations

The TAS5717PHP is a closely related variant within the same family. Verify if the 'L' suffix denotes a specific tape-and-reel configuration or minor parameter adjustment rather than a functional change before substituting.
