TAS5352ADDV

Overview

The TAS5352ADDV is a high-performance Class-D digital audio amplifier power stage from Texas Instruments, housed in a 44-pin HTSSOP (DDV) package. It utilizes a PWM digital input architecture and supports up to four single-ended channels, two bridge-tied load (BTL) channels, or one parallel bridge-tied load (PBTL) channel. In BTL mode with a 4Ω load, it delivers 125W per channel at 10% THD+N. The PBTL configuration provides up to 250W into a 2Ω load. The device operates with a power supply voltage range of 0V to 37V and features an 80mΩ low on-resistance MOSFET output stage.

Feature Summary

• Integrates TI Equibit technology for simplified system design using passive demodulation filters when paired with compatible modulators.
• Includes comprehensive on-chip self-protection mechanisms such as under-voltage lockout, over-temperature warning, overload protection, short-circuit protection, and PWM activity detection.
• Features a built-in power-on reset circuit that eliminates complex power sequencing requirements typically found in traditional amplifier designs.

Applications

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

Procurement Notes

Verify the specific suffix and revision level against the manufacturer's current datasheet before procurement. Confirm compatibility with the intended digital modulation source, such as TI Equibit modulators. Ensure the PCB layout adheres to recommended thermal and EMI guidelines to maintain performance standards. Check for any recent product lifecycle notices regarding availability or obsolescence status.
