TAS5110ADADRG4

Overview

The TAS5110ADADRG4 is a Texas Instruments True Digital Audio Amplifier power stage in a 32-pin PowerPAD TSSOP package. It delivers up to 50 W RMS into a 6-ohm load at 10% THD or 40 W RMS at 0.1% THD. The device operates with a 3.3 V digital interface and accepts mono PWM inputs to drive an internal CMOS H-bridge. Efficiency exceeds 90%, reducing heat sink requirements. Built-in protections include overcurrent, overtemperature, and undervoltage lockout.

Feature Summary

• Integrates Equibit and PurePath Digital technology for high-performance true-digital audio amplification
• Features a self-protecting design with automatic shutdown on fault conditions
• Includes two dedicated bootstrapped gate drives and internal low-dropout voltage regulators
• Provides open-drain error reporting pins for system monitoring

Applications

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

Procurement Notes

Verify the specific ordering suffix 'G4' indicates lead-free and RoHS compliance status. Confirm the DAD package variant matches the required thermal pad orientation. Check current production status as this component may be classified as Not Recommended for New Designs (NRND). Ensure compatibility with TAS50xx series PWM processors for proper system integration.

Selection Notes

Select this component when designing systems requiring high-efficiency digital amplification with minimal external power supplies. The integrated LDOs reduce bill of materials by eliminating external regulator components. Verify that the PCB layout supports the exposed thermal pad for adequate heat dissipation. Ensure the application utilizes a TAS50xx controller to provide the necessary differential PWM signals.

Part Context

This part belongs to the TAS5110A family of True Digital Audio Amplifiers from Texas Instruments. It is designed to work in conjunction with TAS50xx digital audio PWM processors. The product line utilizes TI's proprietary Equibit technology to achieve high output power within a compact surface-mount footprint suitable for consumer electronics.
