Overview
The TPA3100D2RGZT is a stereo Class-D audio power amplifier manufactured by Texas Instruments. It delivers 21.8 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 fixed gain of 36 dB and maintains a total harmonic distortion plus noise of 0.11%. It operates on a single power supply type and includes analog inputs. The component is housed in a 48-VQFN package, supports surface mount installation, and functions within a temperature range of -40°C to +85°C.
Feature Summary
- Stereo Class-D architecture for high-efficiency audio amplification
- Integrated differential input capability
- Built-in protection mechanisms including thermal shutdown and short-circuit protection
- Supports mute and shutdown control functions
Applications
- Portable audio devices requiring high efficiency
- Desktop speakers and soundbars
- Home theater systems
- Professional audio equipment
Procurement Notes
Verify the specific suffix RGZT to confirm the 48-VQFN package variant. Ensure compatibility with the required 10 V to 26 V single supply voltage. Confirm moisture sensitivity level 3 handling requirements during assembly. Validate that the 36 dB fixed gain meets system design specifications without external attenuation.
Selection Notes
Select this component when a stereo Class-D solution is needed with up to 21.8 W per channel at 8 ohms. It is suitable for designs constrained by the 48-VQFN footprint. Consider the 10 V minimum supply requirement against available power rails. The fixed 36 dB gain simplifies signal chain design but limits adjustable volume control options within the amplifier stage.
Part Context
This part belongs to the TPA3100D2 series of stereo audio amplifiers. It shares core performance characteristics with variants like TPA3100D2RGZR and TPA3100D2PHP, differing primarily in packaging and reel configuration. The series is designed for applications demanding high power density and low distortion in compact form factors.
Replacement Considerations
TPA3100D2RGZR offers identical electrical performance in a tape-and-reel format. TPA3100D2PHP provides the same functionality in an HTQFP-48 package. Verify pinout compatibility and thermal dissipation requirements when substituting between these package types.
