TAS5753MDDCA

Overview

The TAS5753MDDCA is a digital input audio power amplifier manufactured by Texas Instruments. It features a Class-D architecture with closed-loop I2S input, designed for stereo applications driving 4-ohm loads. The device delivers an output power of 50W per channel and supports up to 100W in parallel bridge-tied load (PBTL) configuration. Key electrical parameters include a supply voltage range of 8V to 26.4V, a total harmonic distortion plus noise (THD+N) of 0.04%, and a fixed gain of 30dB. It operates within a temperature range of -40°C to +85°C and is housed in a 48-pin HTSSOP package.

Feature Summary

• Integrates a fully programmable data path for routing discrete audio channels from serial data inputs to internal drivers.
• Includes built-in equalization (EQ) and three-band adaptive gain limiting (AGL) for signal processing.
• Supports seamless integration with digital audio processors and MPEG decoders via wide-range input data acceptance.

Applications

• Driving stereo speakers configured in bridge-tied load (BTL) topology
• High-power single-speaker setups using parallel bridge-tied load (PBTL) mode
• Integration with digital audio processors and MPEG decoders

Procurement Notes

Verify the specific suffix 'DDCA' against the manufacturer's official datasheet to confirm the tube packaging format and pinout compatibility. Ensure the design accounts for the specified thermal requirements for the HTSSOP-48 package under maximum load conditions. Cross-reference the ordering part number with current Texas Instruments documentation to validate availability and manufacturing status before finalizing procurement plans.

Selection Notes

Select this component when a high-efficiency Class-D solution with integrated digital signal processing is required. It is suitable for designs needing precise gain control and protection features without external DSP hardware. Consider the 48-pin HTSSOP footprint for PCB layout constraints and verify that the system power supply can support the 8V to 26.4V operating range for the desired output power levels.

Part Context

This device belongs to the TAS575x series of digital audio amplifiers from Texas Instruments. It shares architectural similarities with models like the TAS5751M and TAS5754M but distinguishes itself through the inclusion of adaptive gain limiting and equalization capabilities. The series targets high-fidelity audio applications requiring robust digital interfaces and efficient power delivery in compact packages.

Replacement Considerations

The TAS5753MDCA is a direct alternative differing only in packaging type. Other members of the TAS575x family may serve as functional substitutes if their specific feature sets, such as EQ or AGL, align with the application requirements.
