TPA3251D2DDVR

Audio Amplifiers Overview

The TPA3251D2DDVR is a high-performance Class-D audio amplifier from Texas Instruments, housed in a 44-pin HTSSOP package. It delivers up to 175 W per channel into 4-ohm loads and 350 W in mono configuration. The device operates on a single supply voltage ranging from 12 V to 36 V. It features ultra-low distortion of 0.005% THD+N and supports load impedances of 2 ohms and 4 ohms. Designed for surface-mount installation, it functions within an operating temperature range of 0°C to +70°C.

• Features a 2V RMS analog input interface optimized for compatibility with high-performance digital-to-analog converters.
• Provides high power efficiency combined with ultra-low quiescent power consumption of less than 1W.

Audio Amplifiers Applications

• Active loudspeakers
• AV receivers
• High-end soundbars
• Home theater-in-a-box systems

Audio Amplifiers Procurement Notes

Verify the specific suffix 'D2' against official documentation to confirm pinout and functional specifications. Ensure the HTSSOP-44 package dimensions match the target PCB footprint. Confirm that the 12V to 36V single-supply requirement aligns with the system power architecture. Validate thermal management solutions for the specified output power levels.

Audio Amplifiers Selection Notes

Select this component when designing high-fidelity audio systems requiring substantial power output in a compact form factor. The integrated PurePath™ technology reduces external component count while maintaining audiophile-grade performance. Consider the 2V RMS input sensitivity when pairing with source components. Evaluate the thermal dissipation capabilities of the HTSSOP-44 package for the intended enclosure environment.
