TPA3101D2RGZT

Overview

The TPA3101D2RGZT is a stereo Class-D audio power amplifier manufactured by Texas Instruments. It delivers 10 W of continuous output power 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 includes analog differential inputs. The component is housed in a 48-pin VQFN package and supports surface-mount installation.

Feature Summary

• Stereo Class-D architecture for high-efficiency audio amplification
• Integrated thermal and short-circuit protection mechanisms
• Supports mute and shutdown control functions

Applications

• Portable audio devices requiring efficient power delivery
• Desktop speakers and multimedia systems
• Home theater audio subsystems

Procurement Notes

Verify the specific suffix 'RGZT' against official datasheets to confirm tape-and-reel packaging specifications. Ensure compatibility with existing PCB footprints for the 48-VQFN package. Confirm moisture sensitivity level requirements during storage and handling procedures prior to assembly.

Selection Notes

Select this model when a 10 W per channel output is sufficient for the target application. Compare against the TPA3100D2 series if higher power output near 20 W is required. Verify that the 36 dB fixed gain aligns with the source signal levels without requiring additional pre-amplification stages.

Part Context

This component belongs to the TPA3101D2 family of stereo Class-D amplifiers. It shares core architectural similarities with the TPA3100D2 but offers lower output power ratings. The RGZR variant provides identical electrical characteristics but differs in packaging format, utilizing reel distribution instead of cut tape.
