TAS5110DADG4

Overview

The TAS5110DADG4 is a high-performance true digital audio amplifier power stage from Texas Instruments, designed to drive 50 W per channel. It utilizes Equibit technology and accepts mono PWM 3.3-V inputs to control an internal CMOS H-bridge. The device operates with a digital supply of 3 V to 3.6 V and high-voltage supplies ranging from 16.5 V to 26.5 V. It features over-current, over-temperature, and under-voltage protections within a thermally enhanced 32-pin TSSOP package.

Feature Summary

• Integrates self-protecting design with built-in over-current, over-temperature, and under-voltage safeguards for the H-bridge and speakers.
• Accepts differential 3.3-V digital PWM inputs to control switching of an internal CMOS H-bridge architecture.
• Includes two dedicated bootstrapped gate drives and on-chip low-dropout voltage regulators to minimize external power requirements.

Applications

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

Procurement Notes

Verify that the specific ordering suffix matches the required thermal performance and operating temperature range. Confirm the package orientation, as the DAD variant places the PowerPAD on top rather than the bottom. Ensure compatibility with the intended TAS50xx digital audio PWM processor for proper system integration and signal interfacing.

Selection Notes

Select this component when designing systems requiring high-efficiency digital amplification exceeding 90%. It is suitable for applications needing significant power output into 6-ohm or 8-ohm loads while maintaining low total harmonic distortion. Consider the thermal management requirements associated with the exposed pad design for optimal heat dissipation in compact enclosures.

Part Context

This part belongs to the TAS5110 family of true digital audio amplifier power stages. It is specifically engineered to work in conjunction with Texas Instruments' TAS50xx series digital audio PWM processors. Together, these components deliver high-power audio amplification with system performance capable of achieving less than 0.09% THD.

FAQ

How does the TAS5110 handle fault conditions?

The device includes self-protection mechanisms for over-current, over-temperature, and under-voltage. Faults can latch the shutdown state or force outputs to a disabled state, which can be cleared by asserting the RESET signal.

What is the function of the LDROUT pins?

The LDROUTA and LDROUTB pins provide outputs from internal low-dropout voltage regulators dedicated to the half-bridges and gate drivers. These are for internal use only and must not supply current to external circuitry.
