TAS5342LAADDV

Overview

The TAS5342LAADDVR is a Texas Instruments PurePath Digital Class-D audio amplifier IC housed in a 44-HTSSOP package. It supports mono, stereo, and quad-channel configurations with a supply voltage range of 10.8 V to 13.2 V. The device delivers up to 100 W output power at 4 Ohms or 200 W at 2 Ohms. Key electrical parameters include a THD+N of 0.09% and operating temperatures from 0°C to +70°C.

Feature Summary

• Accepts digital PWM input signals for direct processing
• Integrates short-circuit and thermal protection mechanisms
• Supports shutdown functionality for power management

Applications

• High-power home theater systems
• Professional audio amplification stages
• Multi-channel speaker array drivers

Procurement Notes

Verify the exact suffix (e.g., ADDVR vs. LDDVR) against the datasheet, as variations exist within the family. Confirm RoHS compliance status and moisture sensitivity level requirements before integration. Check current production status, as some variants are marked Not Recommended for New Designs.

Selection Notes

Select this component when high-efficiency digital audio amplification is required for multi-channel setups. Ensure the host system provides compatible digital PWM inputs. Verify that the PCB layout accommodates the 44-pin HTSSOP footprint and thermal dissipation needs for the intended power output levels.

Part Context

This part belongs to the TAS5342L series of PurePath Digital amplifiers. It is designed for high-performance audio applications requiring multiple channels and robust protection features. The series integrates advanced digital signal processing capabilities directly into the power stage.

Replacement Considerations

TAS5342LADDVR is listed as a direct substitute for the TAS5342LDDVR variant.
