TAS5342LADDV

Overview

The TAS5342LADDVR is a Texas Instruments audio amplifier belonging to the PurePath Digital series. It features a Class-D power stage with configurable output types supporting 1-channel mono, 2-channel stereo, or 4-channel stereo configurations. The device delivers up to 100W of output power into a 4-ohm load. Key electrical parameters include a THD+N of 0.09%, operating supply voltage range from 10.8V to 13.2V, and single digital PWM input. It utilizes an HTSSOP-44 package and operates within a temperature range of 0°C to +70°C.

Feature Summary

• Supports flexible multi-channel audio output configurations including mono, stereo, and quad-stereo modes.
• Integrates digital PWM input interface for direct connection to digital audio sources.
• Includes built-in short-circuit and thermal protection mechanisms for enhanced reliability.

Applications

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

Procurement Notes

Verify the specific suffix (e.g., ADDVR vs. LDDVR) against design requirements as variants differ in class and impedance ratings. Confirm RoHS compliance status via official datasheets. Check component lifecycle status, as some variants may be marked as not recommended for new designs. Ensure ESD handling protocols are followed due to humidity sensitivity classification.

Selection Notes

Select this component when high-efficiency Class-D amplification is required for multi-channel setups. Compare output power capabilities at specific load impedances (2 ohms vs. 4 ohms) against system speaker requirements. Evaluate thermal management needs given the 100W power rating. Verify compatibility with available digital audio interfaces and supply voltage constraints.

Part Context

This part belongs to the TAS5342LA family of digital power amplifiers designed for high-performance audio applications. It integrates the power stage and control logic into a single compact package. The family supports various channel configurations to accommodate different speaker arrangements in consumer and professional audio equipment.

Replacement Considerations

TAS5342LADDVR is listed as a direct substitute for TAS5342LDDVR. Note that while functionally similar, verify specific electrical characteristics such as amplifier class and load impedance ratings before swapping, as datasheet specifications may vary between these suffixes.
