Overview
The TPA3101D2RGZR is a stereo Class-D audio power amplifier manufactured by Texas Instruments. It delivers 10 W per channel into an 8-ohm load with a supply voltage range of 10 V to 26 V. The device features a fixed gain of 36 dB and achieves a total harmonic distortion plus noise (THD+N) of 0.09%. It operates on a single power supply and utilizes analog differential inputs. The component is housed in a 48-pin VQFN package measuring 7x7 mm, designed for surface-mount installation.
Feature Summary
- Class-D switching architecture provides high efficiency and reduced thermal requirements compared to linear amplifiers.
- Integrated SpeakerGuard technology monitors speaker impedance and temperature to prevent damage during fault conditions.
- Built-in protection mechanisms include thermal shutdown, short-circuit protection, and pop-and-click suppression circuitry.
Applications
- Active loudspeaker systems
- Soundbars and home theater audio
- Portable PA systems
Procurement Notes
Verify the specific suffix RGZR to confirm the 48-VQFN package and reel packaging format. Ensure the design supports the required 10V to 26V single-supply operation. Confirm that the 8-ohm load impedance matches the target application specifications for optimal 10W performance. Check moisture sensitivity level handling procedures during assembly.
Selection Notes
Select this component when a compact stereo solution is required for 8-ohm loads within a 10V to 26V supply range. It is suitable for designs prioritizing high efficiency and minimal external components. Consider alternative models if higher power output or automotive qualification is necessary. Verify PCB layout constraints for the 48-VQFN package to ensure adequate thermal dissipation.
Part Context
This part belongs to the TPA31xxD2 series of high-efficiency D-class audio amplifiers from Texas Instruments. The series is characterized by low external component counts and integrated protection features. The TPA3101D2 variant specifically targets mid-power stereo applications, offering a balance between performance and board space efficiency.
Replacement Considerations
The TPA3101D2RGZT is a tape-and-reel alternative with identical electrical characteristics. Cross-reference with other TPA31xxD2 family members only if power requirements or package types differ significantly.
