TAS5110DAD

Overview

The TAS5110DAD is a true digital audio amplifier power stage by Texas Instruments, housed in a 32-pin PowerTSSOP 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 and requires high-voltage supplies between 16.5 V and 26.5 V for the H-bridge. It incorporates Equibit technology and functions as a companion to TAS50xx PWM processors.

Feature Summary

• Integrates an internal CMOS H-bridge controlled by differential PWM inputs
• Includes self-protecting design features such as over-current, over-temperature, and under-voltage lockout
• Features two on-chip low-dropout voltage regulators for internal gate drive circuits
• Provides open-drain error reporting outputs for fault conditions

Applications

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

Procurement Notes

Verify component authenticity through authorized channels. Confirm the specific DAD package variant matches thermal requirements. Check datasheet revisions for updates. Ensure system design adheres to recommended operating conditions. Validate pin connections against official documentation.

Selection Notes

Select this component for high-power stereo applications requiring digital input interfaces. Ensure compatibility with TAS50xx series PWM processors. Verify thermal management capabilities match the 50 W output requirement. Confirm supply voltage ranges align with system design constraints.

Part Context

Part of the Equibit family of true digital audio amplifiers. Designed to work with digital audio PWM processors like the TAS5000 or TAS5010. Utilizes TI's proprietary modulation technology for high efficiency and low distortion in audio systems.

Replacement Considerations

TAS5110DAPR is the tape and reel version of the same device. TAS5110IDAD is the industrial temperature range equivalent. TAS5110DADR is the commercial tape and reel option.

FAQ

What is the function of the RESET pin?

The active-low RESET pin forces the H-bridge outputs to a low-low state and clears the short circuit protection latch.

How are the bootstrap capacitors connected?

A capacitor must be connected between the BOOTSTRAPA pin and OUTPUTA pin, and another between BOOTSTRAPB and OUTPUTB.

Can the LDO outputs supply external current?

No, the LDROUTA and LDROUTB pins are for internal gate drive circuits only and must not supply external circuitry.
