Overview
The TAS5721DCA is a digital-input Class-D audio power amplifier manufactured by Texas Instruments. It delivers 15 watts of stereo output power and features an integrated headphone amplifier. The device supports 2.0 speaker systems in bridge-tied load (BTL) configuration and 2.1 systems with two speakers. It includes an integrated audio processor with equalization (EQ) and dynamic range compression (DRC). The component operates within a temperature range of 0 to 85 degrees Celsius and is housed in a 48-pin HTSSOP package.
Feature Summary
- Digital input architecture for efficient audio amplification
- Integrated audio processing capabilities including EQ and DRC
- Supports versatile speaker configurations such as 2.0 BTL and 2.1 systems
- Includes an integrated headphone amplifier for direct drive
Applications
- Driving 2.0 stereo speaker systems
- Powering 2.1 surround sound speaker setups
- Headphone amplifier integration
- Digital audio processing units
Procurement Notes
Verify the specific ordering suffix to confirm the tape and reel configuration, as the base part number may correspond to different packaging options like tube or reel. Ensure the voltage ratings and thermal requirements align with the target system design before finalizing procurement. Cross-reference the datasheet revision date to ensure compatibility with current manufacturing standards.
Selection Notes
Select this component when a high-efficiency digital interface is required alongside built-in signal processing functions. It is suitable for designs needing both speaker and headphone outputs from a single IC. Consider the 48-pin HTSSOP package constraints for PCB layout. Verify that the system can provide the necessary digital clock signals and I2C control lines for configuration.
Part Context
This device belongs to the TAS5721 family of digital audio amplifiers. Variants such as the TAS5721DCAR share identical electrical characteristics but differ in packaging format. The family is designed for applications requiring compact solutions with integrated audio enhancement features, distinguishing it from basic power amplifiers lacking internal DSP capabilities.
Replacement Considerations
The TAS5721DCAR serves as a functional substitute with identical performance specifications, differing only in the reel-based packaging format compared to the tube version. No other cross-model replacements are confirmed in the provided documentation.
