TAS5719PHP

Overview

The TAS5719PHP is a digital input stereo audio power amplifier manufactured by Texas Instruments. It utilizes Class-D topology to deliver high-efficiency audio amplification within a compact HTQFP-48 surface-mount package. The device operates across a supply voltage range of 8 V to 26 V and supports an operating temperature range from 0°C to +85°C. Designed for serial digital interfaces, it integrates features such as speaker equalization and dynamic range compression to optimize audio performance in consumer electronics applications.

Feature Summary

• Integrates digital signal processing capabilities including speaker equalization and two-band dynamic range compression.
• Supports serial digital audio inputs for direct connection to digital audio sources.
• Delivers stereo output power with high efficiency using Class-D architecture.

Applications

• Portable multimedia devices requiring efficient stereo amplification
• Digital audio systems utilizing I2S or similar serial interfaces
• Consumer electronics with space-constrained PCB layouts

Procurement Notes

Verify the specific suffix (PHP vs PHPR) against the manufacturer's official datasheet to confirm packaging type, as PHP typically denotes tray packaging while PHPR indicates reel packaging. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Ensure the ordering quantity aligns with the specified factory pack configuration to avoid handling discrepancies during assembly.

Selection Notes

Select this component when a digital input interface is required rather than analog line-level inputs. Evaluate the thermal dissipation requirements associated with the HTQFP-48 package under maximum load conditions. Compare power output specifications at 8-ohm versus 4-ohm loads to ensure compatibility with the target speaker impedance. Verify that the system power supply can maintain stability within the 8 V to 26 V operational window.

Part Context

This part belongs to the TAS5719 series of digital audio amplifiers from Texas Instruments. It shares the same HTQFP-48 footprint and core functionality with other variants in the family, differing primarily in packaging format and minor electrical characteristics. The series is designed for modern digital audio architectures replacing traditional Class-AB amplifiers in portable and fixed installations.

Replacement Considerations

Direct replacements include TAS5719PHPR for identical functionality with reel packaging. Cross-reference TAS5713PHPR if higher power output or different gain settings are acceptable. Verify pin-to-pin compatibility and software configuration registers before substituting with other TAS57xx series devices.
