Overview
The TAS5112DFDR is a digital amplifier power stage from Texas Instruments, part of the PurePath Digital series. It features a stereo D-class output architecture housed in a 56-HTSSOP package. The device operates within a supply voltage range of 16V to 25.5V and supports an operating temperature range of 0°C to 70°C. It delivers up to 37W per channel into a 6-ohm load. Key integrated protections include pop-and-click suppression, mute functionality, short-circuit protection, thermal shutdown, and shutdown control.
Feature Summary
- Digital input interface for direct connection to audio processors
- Integrated pop-and-click suppression for silent startup and shutdown
- Comprehensive protection mechanisms including thermal foldback and short-circuit defense
Applications
- Automotive infotainment systems
- Home theater receivers
- Active loudspeaker designs
Procurement Notes
Verify component authenticity through authorized distributors or TI directly. Confirm package integrity and pin alignment upon receipt. Check manufacturing date codes against project timelines. Ensure storage conditions comply with moisture sensitivity level requirements. Validate datasheet revisions match design specifications.
Selection Notes
Select this component when a high-power digital input amplifier is required for stereo applications. It suits designs needing robust protection features and direct digital connectivity. Consider the 56-pin HTSSOP footprint for PCB layout constraints. Evaluate thermal management needs based on the 37W per channel capability at 6 ohms.
Part Context
This device belongs to Texas Instruments' PurePath Digital amplifier family. It complements other TAS series components like the TAS5111 and TAS5121. These parts share similar digital control interfaces but vary in channel count and power output. The TAS5112 targets mid-to-high power stereo applications requiring efficient class-D performance.
Replacement Considerations
Check for TAS5112ADCAR or TAS5112ADCA variants which may offer different packaging or temperature grades. Verify pin compatibility before substitution. Consult official TI documentation for any functional differences between suffixes.
