TAS5782MDCAR

Overview

The TAS5782MDCAR is a digital input Class-D smart audio amplifier manufactured by Texas Instruments. It delivers 20W stereo or 40W mono output with a power supply voltage range of 4.5V to 26.4V. The device integrates an audio processor supporting up to 96kHz sampling rates and features a closed-loop architecture for high fidelity. It is housed in a 48-pin HTSSOP package with an exposed pad, designed for surface mount installation across an operating temperature range of -25°C to 85°C.

Feature Summary

• Integrates a µCDSP audio processing core with SmartEQ, crossover, dynamic EQ, and spatialization capabilities.
• Supports flexible digital audio inputs including I2S, TDM, Left-Justified, and Right-Justified formats without requiring MCLK.
• Employs a closed-loop architecture that reduces external component count while maintaining low noise and distortion.
• Includes comprehensive protection mechanisms such as clock error detection, DC fault, short circuit, overtemperature, and overcurrent safeguards.

Applications

• LCD and LED televisions
• Sound bars and multimedia displays
• Wireless subwoofers and Bluetooth speakers
• Docking stations and PC audio systems

Procurement Notes

Verify the specific suffix 'DCAR' indicates tape-and-reel packaging distinct from the tube-packaged 'MDCA' variant. Confirm the device status remains active as manufacturing schedules may change. Ensure compatibility with the target system's I2C control interface and digital audio protocol requirements before finalizing procurement.

Selection Notes

Select this component when a high-performance stereo amplifier with integrated digital signal processing is required. It is suitable for designs needing a closed-loop topology to minimize passive components. Consider the 48-pin HTSSOP footprint for space-constrained applications. Verify that the host controller supports the necessary I2C configuration and digital audio interfaces.

Part Context

This part belongs to the Texas Instruments TAS5782M family of smart audio amplifiers. It shares architectural similarities with the TAS5780M but offers enhanced processing features. The device is part of TI's portfolio of digital input Class-D amplifiers designed for consumer electronics requiring high sound quality and compact form factors.

Replacement Considerations

The TAS5782MDCA is a pin-compatible alternative available in tube packaging. Engineers should verify if the packaging difference impacts assembly processes. No other direct substitutes are confirmed in the provided documentation.
