Overview
The TPA3100D2PHP is a stereo Class-D audio power amplifier manufactured by Texas Instruments. It delivers 21.8 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 of 0.11%. It operates on a single power supply and includes analog inputs. The component is housed in a 48-pin HTQFP package and supports surface-mount installation. Operating temperatures range from -40°C to +85°C, with a quiescent current of 18 mA.
Feature Summary
- Integrated differential output architecture for high-fidelity stereo audio reproduction
- Built-in thermal overload and short-circuit protection mechanisms
- Supports mute and shutdown control functions for system management
Applications
- Active loudspeaker systems
- Soundbars and home theater audio receivers
- Portable public address equipment
Procurement Notes
Verify the exact suffix against official manufacturer documentation to confirm packaging type and compliance status. Ensure the ordering part number matches the required tray quantity and RoHS specifications. Cross-reference datasheet revisions to validate pinout compatibility and electrical characteristics before procurement.
Selection Notes
Select this component for applications requiring high-efficiency stereo amplification within a compact form factor. Consider the 48-pin HTQFP package constraints for thermal management and PCB layout. Evaluate the 10 V to 26 V supply requirement against available system power rails to ensure adequate headroom for the specified output power levels.
Part Context
This device belongs to the TPA3100D2 series of Class-D audio amplifiers. It shares core architectural similarities with other members like the TPA3101D2 but offers distinct power output capabilities. The PHP suffix indicates a specific tray-packaged variant within the broader product family designed for high-volume manufacturing integration.
Replacement Considerations
The TPA3100D2PHPG4 serves as a verified lead-free replacement variant within the same series. Verify pin compatibility and thermal performance when substituting.
