TAS5352DDVG4

Overview

The TAS5352DDVG4 is a high-performance Class-D digital audio amplifier power stage from Texas Instruments, utilizing a PWM digital input architecture. It operates in a 44-pin HTSSOP package and delivers up to 125W per channel in bridge-tied load (BTL) mode with 10% THD+N at 4Ω, or 250W in parallel bridge-tied load (PBTL) mono mode. The device features Equibit technology for compatibility with TI modulation solutions, low on-resistance output MOSFETs exceeding 90% efficiency, and integrated protection circuits including undervoltage lockout, overtemperature, and short-circuit protection.

Feature Summary

• Digital PWM input architecture compatible with Equibit modulators
• High-efficiency power stage with low harmonic distortion
• Integrated comprehensive self-protection mechanisms

Applications

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

Procurement Notes

Verify the specific suffix 'G4' against official Texas Instruments documentation to confirm RoHS compliance status and current lifecycle designation. Ensure the ordering part number matches the exact package variant required for your PCB footprint. Cross-reference the datasheet revision history to validate pinout consistency before finalizing procurement orders.

Selection Notes

Select this component when designing high-power audio systems requiring direct digital PWM inputs to eliminate external DACs. It is suitable for applications demanding high channel density and thermal efficiency within compact enclosures. Verify that the host system provides compatible PWM signals and that the power supply rails meet the specified requirements for the desired output power levels.

Part Context

This device belongs to the TAS5352A series of D-class audio amplifiers designed for high-fidelity, high-power applications. It represents a power-stage solution intended to be paired with digital front-end processors. The series emphasizes simplified system design through reduced external component count and robust integration of protective features for reliable operation in consumer audio environments.

Replacement Considerations

Check for the TAS5352ADDVR as a potential alternative within the same family. Confirm functional equivalence and pin compatibility before substitution.
