Overview
The TAS5782MDCA is a digital input Class-D smart audio amplifier manufactured by Texas Instruments. It delivers 20W stereo or 40W mono output with a 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 operates within a temperature range of -25°C to 85°C and is housed in a 48-pin HTSSOP package.
Feature Summary
- Integrates a µCDSP audio processing core with SmartEQ, crossover filters, dynamic EQ, and spatialization capabilities.
- Supports flexible digital audio inputs including I2S, TDM, Left-Justified, and Right-Justified formats without requiring MCLK.
- Features a closed-loop amplifier architecture that reduces external component count while maintaining low distortion and noise.
- 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 docking stations
- PC audio systems
- Wireless subwoofers and Bluetooth speakers
Procurement Notes
Verify the specific suffix MDCA corresponds to the tube packaging format when sourcing. Confirm RoHS compliance status and lead times directly with authorized distributors. Ensure the procurement channel provides valid traceability documentation for this active component.
Selection Notes
Select this model for applications requiring integrated DSP functions alongside power amplification. It is suitable for designs needing a single-chip solution for stereo or mono Class-D outputs. Consider the 48-pin HTSSOP footprint for PCB layout constraints.
Part Context
This component belongs to the TAS5782M family of intelligent audio amplifiers from Texas Instruments. It is designed to replace discrete amplifier and DSP solutions, offering a compact alternative for modern audio systems. The part is currently classified as active in the manufacturer's portfolio.
Replacement Considerations
The TAS5782MDCAR is a verified substitute variant featuring tape-and-reel packaging instead of tubes. Both parts share identical electrical specifications and functionality.
