TAS5342DDV

Overview

The Texas Instruments TAS5342DDV is a Class-D audio amplifier housed in an HTSSOP-44 package. It delivers 100 W of output power into a 4 Ohm load with a THD+N of 0.09%. The device operates on a triple power supply within a voltage range of 10.8 V to 13.2 V. It supports differential inputs and offers configurable channel modes, including 1-channel mono, 2-channel stereo, or 4-channel stereo operation. The component functions within an ambient temperature range of 0°C to +70°C.

Feature Summary

• Class-D architecture for high-efficiency audio amplification
• Configurable multi-channel output topology
• Differential input signal interface

Applications

• High-power stereo audio systems
• Mono audio power stages
• Multi-channel surround sound configurations

Procurement Notes

Verify the current lifecycle status before procurement, as this component may be marked as Not Recommended for New Designs (NRND). Confirm that the HTSSOP-44 surface-mount package aligns with your PCB footprint requirements. Ensure the design accommodates the specified triple power supply rails and thermal management needs for the 100W output capability. Check for moisture sensitivity handling procedures during assembly.

Selection Notes

Select this part when a Class-D solution with differential inputs and high power density is required. Compare against the TAS5342ADDV if single-ended inputs are preferred instead of differential. Consider the operating temperature range and package constraints. Verify compatibility with the intended load impedance and supply voltage specifications to ensure optimal performance and reliability in the target application.
