Overview
The TAS5755MDFD is a digital input Class-D audio amplifier manufactured by Texas Instruments, housed in a 56-pin HTSSOP package. It supports mono or stereo configurations with a supply voltage range of 8 V to 26.4 V and operates within a temperature range of 0°C to +125°C. The device delivers up to 50 W of output power into a 4-ohm load. Key electrical specifications include a total harmonic distortion plus noise (THD+N) of 0.1% and a shutdown feature for power management.
Feature Summary
- Supports digital audio inputs for direct integration with digital signal processors
- Integrates thermal protection and short-circuit protection mechanisms
- Configurable for mono or stereo operation modes
Applications
- Home theater systems
- Portable audio devices
- Automotive infotainment systems
Procurement Notes
Verify the specific suffix 'FD' against the manufacturer's official datasheet to confirm pinout and packaging details. Ensure compatibility with the required 56-HTSSOP footprint during PCB design. Confirm moisture sensitivity level requirements for assembly processes. Validate that the digital input interface matches the source component specifications.
Selection Notes
Select this component when high efficiency and digital connectivity are required. The wide supply voltage range allows flexibility in power supply design. Consider the thermal performance characteristics given the high power output capability. Ensure the application environment stays within the specified operating temperature limits for reliable performance.
Part Context
This part belongs to the TAS5755M series of digital audio amplifiers from Texas Instruments. The series is designed for applications requiring high power output with low distortion. The DFDR variant typically indicates reel packaging, while the DFD variant may indicate tube packaging, though verification is necessary.
Replacement Considerations
Check for TAS5755MDFDR as a potential alternative if reel packaging is preferred. Verify functional equivalence with other members of the TAS5755M family before substitution.
