TAS5755MDFDR

Overview

The TAS5755MDFDR is a digital input Class-D audio amplifier manufactured by Texas Instruments, housed in a 56-pin HTSSOP package. It supports four-channel stereo operation with an output power of 50 W and delivers 100 W in mono configuration. The device operates within an 8 V to 26.4 V supply voltage range and maintains a total harmonic distortion plus noise of 0.1%. Designed for surface-mount installation, it functions reliably between 0°C and +125°C junction temperature.

Feature Summary

• Digital input interface for direct connection to digital audio sources
• Integrated thermal and short-circuit protection mechanisms
• Configurable for both stereo and mono bridge-tied load applications

Applications

• High-power home theater systems
• Professional audio amplification equipment
• Automotive infotainment speaker drivers

Procurement Notes

Verify the specific suffix DR indicates reel packaging when ordering. Confirm the 56-HTSSOP footprint matches the target PCB layout. Ensure the design supports the required 8V to 26.4V input range. Check moisture sensitivity level requirements for storage and handling procedures prior to assembly.

Selection Notes

Select this component for designs requiring high-efficiency digital amplification with significant power output. The wide supply voltage range accommodates various battery and rail configurations. Consider the thermal management needs associated with 50W stereo operation in enclosed spaces.

Part Context

This part belongs to the TAS5755M series of digital audio amplifiers from Texas Instruments. It is distinct from lower-power variants like the TAS5751M and serves as a high-performance solution for demanding audio applications requiring robust power delivery and digital integration.

Replacement Considerations

TAS5755MDFD is a tube-packaged variant of the same functional device.
