TAS5352DDVR

Overview

The TAS5352DDVR is a Texas Instruments Class-D digital audio amplifier power stage in a 44-pin HTSSOP package. It delivers up to 125W per channel in stereo bridge-tied load (BTL) mode and 250W in parallel bridge-tied load (PBTL) mono mode at 4Ω with 10% THD+N. The device features differential PWM input, supports frame rates from 192kHz to 432kHz, and includes integrated protection against over-temperature, short circuits, and undervoltage.

Feature Summary

• Digital PWM input architecture compatible with Equibit modulators
• High efficiency exceeding 90% via low on-resistance MOSFETs
• Integrated self-protection including thermal and short-circuit safeguards

Applications

• Home theater systems
• AV receivers
• Soundbars
• Active subwoofers

Procurement Notes

Verify the specific suffix 'DDV' against official documentation, as it may indicate tube packaging or distinct handling requirements compared to tape-and-reel variants like 'ADDVR'. Confirm current lifecycle status, as some sources suggest this part may be recommended against new designs. Ensure compatibility with your chosen modulation scheme before procurement.

Selection Notes

Select this component for high-power applications requiring direct digital PWM inputs to simplify signal chains. It is suitable where high efficiency reduces thermal management complexity. Verify that the system design accommodates the required PWM frame rates and that the 44-pin HTSSOP footprint fits the mechanical constraints of the target enclosure.

Part Context

This device belongs to the TAS5352A series of high-performance D-class audio amplifiers. It is designed to work with TI's Equibit technology, allowing for simple passive demodulation filters. The series targets high-fidelity audio markets by combining high output power with low distortion and noise characteristics.

Replacement Considerations

TAS5352ADDVR is a verified alternative within the same family, typically differing in packaging format.
