TAS5162DKDR

Overview

The TAS5162DKDR is a stereo digital amplifier power stage from Texas Instruments, housed in a 36-pin PSOP3 package. It delivers high-efficiency audio amplification with output power of 2x160 W into 8-ohm BTL loads and 2x210 W into 6-ohm BTL loads at 10% THD+N. The device operates on two power supplies: 12 V for GVDD/VDD and 50 V for PVDD. It features greater than 90% efficiency, an SNR exceeding 110 dB (A-weighted), and integrated self-protection circuits including undervoltage, overtemperature, overload, and short-circuit protection.

Feature Summary

• High-efficiency Class-D architecture with intelligent gate drive and programmable overcurrent detection.
• Integrated self-protection system featuring undervoltage, overtemperature, overload, and short-circuit safeguards.
• Flexible mode selection via hardwired pins to support BTL, PBTL, and single-ended output configurations.
• EMI compliant design requiring only a simple passive LC demodulation filter.

Applications

• Mini/Micro Audio Systems
• DVD Receivers
• Home Theater

Procurement Notes

Verify the specific suffix DKDR against the manufacturer's current ordering information to confirm package type and tape-and-reel availability. Ensure compatibility with the required thermal management solutions, as the PSOP3 package relies on top-side thermal coupling for heat dissipation. Cross-reference the component marking with official datasheets to authenticate the source and production batch.

Selection Notes

Select this component when designing high-power stereo audio systems requiring efficient digital amplification. It is suitable for applications needing flexible output configurations through M1-M3 pin settings. Consider the thermal requirements carefully, as the DKD package has a smaller pad area compared to the DDV variant, making the thermal interface to the heatsink critical for maintaining performance under full load conditions.

Part Context

The TAS5162 belongs to Texas Instruments' PurePath Digital family of Class-D audio amplifiers. It is designed to work in conjunction with PWM processors like the TAS5508 to create complete high-fidelity audio solutions. The DKD suffix specifically denotes the 36-pin PSOP3 thermally enhanced package, distinguishing it from the 44-pin HTSSOP PowerPad option available in the same product line.
