Overview
The TPA3101D2RGZTG4 is a stereo Class-D audio power amplifier manufactured by Texas Instruments. It delivers 10 W of continuous output power per channel into an 8-ohm load with a supply voltage range of 10 V to 26 V. The device features a total harmonic distortion plus noise (THD+N) of 0.09% and operates with a fixed gain of 36 dB. It utilizes analog inputs and provides differential outputs within a 48-pin VQFN package. The component supports single-supply operation and functions across a temperature range of -40°C to +85°C.
Feature Summary
- Delivers high-efficiency stereo audio amplification using Class-D topology.
- Integrates comprehensive protection mechanisms including thermal shutdown and short-circuit protection.
- Supports flexible input configurations with analog signal interfaces.
Applications
- Portable multimedia speakers
- Home theater systems
- Audio docking stations
Procurement Notes
Verify the specific suffix 'G4' indicates lead-free compliance and RoHS adherence as documented by Texas Instruments. Confirm the package type matches the required PCB footprint for the 48-VQFN configuration. Ensure the operating environment remains within the specified electrical and thermal limits defined in the official datasheet.
Selection Notes
Select this component when a compact stereo solution is required for 8-ohm loads. The 10 W output rating suits applications where moderate power is sufficient. Consider the 48-VQFN package for space-constrained designs requiring surface-mount assembly.
Part Context
This part belongs to the TPA3101D2 series, designed for efficient audio amplification. It shares architectural similarities with other members like the TPA3100D2 but offers lower power output. The series targets consumer electronics needing reliable stereo performance in small form factors.
Replacement Considerations
The TPA3101D2RGZR serves as a standard tape-and-reel alternative within the same family. Verify pin compatibility and thermal characteristics before substitution.
