TAS5110DADRG4

Overview

The TAS5110DADRG4 is a true digital audio amplifier power stage from Texas Instruments, housed in a 32-pin TSSOP PowerPAD package. It delivers 50 W RMS into a 6 Ω load at 10% THD and 40 W RMS at 0.1% THD. The device operates with a 3.3 V digital interface and requires a high-voltage supply between 16.5 V and 26.5 V. It incorporates Equibit technology for high efficiency exceeding 90%. Built-in protections include over-current, over-temperature, and under-voltage lockout.

Feature Summary

• Integrates an internal CMOS H-bridge controlled by differential PWM inputs
• Includes self-protecting design features such as short-circuit and thermal shutdown
• Features on-chip low-dropout voltage regulators to minimize external components
• Provides open-drain error reporting pins for fault condition 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 suffix 'RG4' indicates RoHS compliance and tape-and-reel packaging configuration. Confirm the DAD package variant matches the required thermal pad orientation for your PCB layout. Ensure the ordering code aligns with the commercial temperature range of 0°C to 70°C. Cross-reference the datasheet revision date to ensure compatibility with current design standards.

Selection Notes

Select this component when designing systems requiring high-power digital amplification with minimal external filtering complexity. It is intended for use with TI TAS50xx digital audio PWM processors. Consider the thermal requirements of the 32-pin TSSOP package for sustained 50 W output. Evaluate the system's ability to provide the necessary 16.5 V to 26.5 V supply rails for optimal performance.

Part Context

This part belongs to the TAS5110 family of True Digital Audio Amplifier (TDAA) power stages. It utilizes Texas Instruments' Equibit technology to achieve high efficiency and low distortion. The device is designed to work in conjunction with digital audio PWM processors like the TAS5000 or TAS5010 series to form complete stereo or multi-channel audio solutions.

Replacement Considerations

TAS5110DAP is the equivalent HTSSOP PowerPAD package version.
