Overview
The TPA3100D2PHPG4 is a stereo Class-D audio power amplifier manufactured by Texas Instruments. It delivers 21.8 W of output power into an 8-ohm load with a total harmonic distortion plus noise of 0.11%. The device operates on a single supply voltage ranging from 10 V to 26 V and features a fixed gain of 36 dB. It utilizes analog inputs and provides differential outputs. The component is housed in a 48-pin HTQFP package, measures 7x7 mm, and supports surface-mount installation. It functions within a temperature range of -40°C to +85°C.
Feature Summary
- Stereo Class-D architecture for high-efficiency audio amplification
- Integrated protection mechanisms including thermal shutdown and short-circuit protection
- Supports mute and shutdown control functions for system management
Applications
- Home theater systems
- Portable multimedia devices
- Active loudspeakers
Procurement Notes
Verify the specific suffix 'PG4' confirms RoHS compliance and lead-free status as per manufacturer specifications. Confirm the HTQFP-48 package dimensions match your PCB footprint requirements. Ensure the single-supply voltage range aligns with your system's power delivery capabilities before finalizing procurement.
Selection Notes
Select this component when a stereo configuration is required rather than mono output. The HTQFP-48 package offers a balance between thermal performance and board space compared to smaller footprints. Consider the fixed 36 dB gain setting against your input signal levels to determine if external attenuation or pre-amplification is necessary for optimal dynamic range.
Part Context
This part belongs to the TPA3100D2 series of audio amplifiers. It shares core electrical characteristics with variants like the TPA3100D2PHPR but differs in packaging format. The PHPG4 designation specifically indicates the tray-packaged version of the HTQFP-48 component, distinguishing it from reel-based alternatives within the same family.
Replacement Considerations
The TPA3100D2PHPR serves as a functional alternative with identical electrical specifications but utilizes a tape-and-reel packaging format instead of trays.
