TAS5352DDV

Overview

The TAS5352DDV is a Texas Instruments Class-D digital audio amplifier power stage in a 44-pin HTSSOP package. It supports 4-channel SE, 2-channel BTL, or 1-channel PBTL configurations. In BTL mode with a 4Ω load, it delivers 2x100W at 10% THD+N. The device features an 80mΩ low Rds(on) MOSFET output stage for efficiency exceeding 90%. It accepts PWM digital inputs and operates with a PVDD of 0V to 37V and VDD of 10.8V to 13.2V. Key performance metrics include a dynamic range of 110dB and total harmonic distortion plus noise under 0.1%.

Feature Summary

• Equibit technology compatibility allows integration with compatible modulators using simple passive demodulation filters.
• Integrated self-protection circuits provide comprehensive safety including undervoltage, overtemperature, overload, short circuit, and PWM activity detection.
• Built-in power-on reset (POR) eliminates complex power sequencing requirements typically found in traditional amplifier designs.
• Supports high-frequency PWM frame rates from 192kHz to 432kHz for high-fidelity audio reproduction.

Applications

• Home theater systems
• AV receivers
• Soundbars
• Active speakers
• Professional audio equipment

Procurement Notes

Verify the specific suffix 'DDV' against current manufacturer documentation, as availability may be limited compared to tape-and-reel variants like 'ADDVR'. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Check for active engineering change notices that might affect pinout or electrical characteristics. Ensure supply chain stability by validating lead times with authorized distributors.

Selection Notes

Select this component for high-power stereo applications requiring digital PWM input interfaces. It is suitable for designs needing integrated protection without external logic. Consider the thermal management requirements associated with its 44-pin HTSSOP package. Verify compatibility with the system's PWM modulation scheme and power supply rails before finalizing the design.

Part Context

This part belongs to the TAS5352A series of high-performance Class-D power stages. It is designed to work in conjunction with Texas Instruments Equibit modulators. The series targets high-fidelity audio markets where efficiency and sound quality are critical. The device simplifies system design by integrating power MOSFETs and control logic into a single solution.

Replacement Considerations

TAS5352ADDVR is a direct substitute offering the same functionality in a tape-and-reel packaging format for automated assembly.
