TAS5751MDCAR

Overview

The TAS5751MDCAR is a digital input Class-D audio power amplifier manufactured by Texas Instruments. It is designed to drive stereo speakers configured as a bridge-tied load (BTL). In parallel BTL mode, it drives a single low-impedance load for higher power output. The device accepts wide-range serial data inputs and integrates with digital audio processors. Key electrical parameters include a 25 W stereo output power at 8 Ohms, a THD+N of 0.1%, and an operating supply voltage range of 3 V to 3.6 V for the logic section. It operates within a temperature range of 0°C to +85°C.

Feature Summary

• Digital input architecture supporting up to two discrete audio channels via a single serial data interface.
• Configurable output topology allowing operation in standard bridge-tied load or parallel bridge-tied load modes.
• Fully programmable data path for routing audio channels to internal speaker drivers.
• Seamless integration capability with most digital audio processors and MPEG decoders.

Applications

• Driving stereo speaker loads in consumer electronics
• Integration with digital audio signal processing systems
• High-efficiency audio amplification in portable devices

Procurement Notes

Verify the specific suffix 'DCAR' indicates the tape-and-reel packaging variant distinct from the tube-packaged 'MDCA'. Confirm that the 3V to 3.6V logic supply specification aligns with your system's voltage rails. Ensure the HTSSOP-48 package dimensions match your PCB footprint requirements. Validate thermal management strategies for the specified 0°C to +85°C operating range.

Selection Notes

Select this component when a digital interface is required instead of analog inputs. It is suitable for applications needing efficient stereo amplification with programmable data routing. Consider the parallel BTL capability if driving lower impedance loads requires increased power delivery compared to standard BTL configurations.

Part Context

This part belongs to the TAS5751M series of PurePath digital audio amplifiers. It shares the same core functionality and pinout with the TAS5751MDCA, differing primarily in packaging format. The series is characterized by high efficiency and digital control features for modern audio systems.

Replacement Considerations

The TAS5751MDCA is a direct functional substitute with identical electrical characteristics, differing only in packaging type. Other TAS575xM series devices may offer different power levels or voltage ranges but require circuit redesign.
