TAS5342DDVRG4

Overview

The TAS5342DDVRG4 is a Class-D audio amplifier manufactured by Texas Instruments, housed in a 44-HTSSOP package. It operates on a supply voltage range of 10.8 V to 13.2 V and supports differential digital PWM inputs. The device delivers up to 100 W into a 4-ohm load in stereo mode or 200 W into a 2-ohm load in mono mode. Key electrical specifications include a THD+N of 0.09% and an operating temperature range from 0°C to +70°C.

Feature Summary

• Supports configurable mono, stereo, or bridge-tied load (BTL) output topologies for flexible system integration.

Applications

• High-fidelity home theater systems
• Powered speaker enclosures
• Audio amplification modules

Procurement Notes

Verify the component status as Not Recommended for New Designs (NRND). Confirm that the specific suffix matches the required tape-and-reel packaging format. Ensure compatibility with existing thermal management solutions due to high power density. Validate input signal levels against the specified differential digital PWM requirements before finalizing procurement.

Selection Notes

Select this component when a high-power, digitally controlled Class-D solution is required for stereo or mono configurations. Consider the 44-pin HTSSOP package constraints for PCB layout. Evaluate the 10.8 V to 13.2 V supply voltage window against available system power rails. Assess thermal dissipation needs given the 100 W continuous output capability.

Part Context

This part belongs to the TAS5342 family of PurePath Digital amplifiers. It is designed for applications requiring high efficiency and low distortion. The device integrates protection features such as short-circuit and thermal shutdown. It serves as a power stage for digital audio processing chains.
