TAS5110ADADR

Overview

The TAS5110ADADR is a true-digital audio amplifier power stage from Texas Instruments, housed in a 32-pin PowerPAD HTSSOP package. It delivers up to 50 W RMS into a 6-ohm load at 10% THD and 40 W RMS at 0.1% THD. The device operates with a 3.3 V digital interface (DVDD) and accepts mono PWM inputs to drive two internal H-bridges for stereo output. High-voltage supplies range from 16.5 V to 26.5 V. It incorporates Equibit technology and offers overcurrent, overtemperature, and undervoltage protection.

Feature Summary

• Accepts differential PWM input signals to control internal CMOS H-bridge switching
• Integrates self-protecting design features including short-circuit, overtemperature, and undervoltage lockout
• Includes on-chip low-dropout voltage regulators dedicated to half-bridge gate drivers
• Utilizes bootstrapped gate drive architecture to minimize external high-voltage supply requirements

Applications

• DVD Receivers
• Home Theater Systems
• Mini/Micro Component Audio Systems
• Internet Music Appliances
• Car Audio Amplifiers and Head Units

Procurement Notes

Verify the specific ordering suffix 'R' indicates tape and reel packaging versus the standard tube configuration. Confirm RoHS compliance status as the component may be classified as Not Recommended for New Designs (NRND). Ensure thermal management designs account for the PowerPAD package requirements to maintain junction temperatures within specified limits during operation.

Selection Notes

Select this component when a high-efficiency digital amplification solution is required for systems utilizing TI TAS50xx PWM processors. The device is suitable for applications demanding high power density in a low-profile surface-mount form factor. Consider the thermal resistance characteristics of the PCB layout when designing for maximum output power capabilities.

Part Context

This part belongs to the TAS5110A family of True Digital Audio Amplifier power stages. It is designed to work in conjunction with digital audio PWM processors such as the TAS5000 or TAS5010. The DAD package variant provides a thermally enhanced footprint optimized for high-power dissipation in compact consumer electronics enclosures.

Replacement Considerations

TAS5110ADADG4 is a lead-free version of the same functional device. Both are listed as Not Recommended for New Designs (NRND). Verify pin compatibility and thermal performance if substituting between tube and reel packaging variants.
