TAS5756MDCA

Overview

The TAS5756MDCA is a digital input, closed-loop Class-D audio amplifier manufactured by Texas Instruments. It features PurePath™ HybridFlow architecture and supports stereo or mono configurations. The device operates with a power supply voltage range of 4.5V to 26.4V. In stereo mode at 4 ohms, it delivers 28W per channel. In mono bridge-tied-load (BTL) mode at 4 ohms, it provides 56W. The total harmonic distortion plus noise (THD+N) is 0.03%. It utilizes I²S, TDM, LJ, and RJ digital audio interfaces.

Feature Summary

• Integrates PurePath™ HybridFlow architecture for configurable MiniDSP programs
• Supports flexible digital audio inputs including I²S, TDM, LJ, and RJ formats
• Provides comprehensive protection mechanisms such as clock error detection and thermal shutdown

Applications

• Bluetooth speakers
• Soundbars
• Docking stations
• Subwoofers

Procurement Notes

Verify the specific suffix 'DCA' indicates tube packaging when sourcing this component. Confirm that the part number matches the exact Texas Instruments designation for the 48-pin HTSSOP package. Ensure compatibility with the required digital audio interface protocols before integration into the design.

Selection Notes

Select this component for applications requiring high-efficiency Class-D amplification with integrated digital signal processing. It is suitable for designs needing up to 56W in mono or 28W per channel in stereo. Consider the 48-pin HTSSOP package constraints and the need for a power supply within the 4.5V to 26.4V range during system planning.

Part Context

This device belongs to the TAS5756M series of digital input closed-loop Class-D amplifiers. It shares architectural similarities with other members like the TAS5754M but offers specific power output characteristics tailored for mid-range audio systems. The series emphasizes ease of use through programmable DSP capabilities while maintaining high audio fidelity.

Replacement Considerations

TAS5756MDAR is an alternative version of the same amplifier core available in cut tape/reel packaging instead of tubes.
