TAS5342LADDVR

Overview

The TAS5342LADDVR 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 10.8V to 13.2V. The device delivers up to 100W per channel into 4-ohm loads or 200W in mono mode into 2-ohm loads. Key electrical specifications include a THD+N of 0.09% and an operating temperature range of 0°C to 70°C.

Feature Summary

• Accepts digital PWM input signals for direct amplification
• Integrates short-circuit and thermal protection mechanisms
• Supports configurable mono, stereo, and four-channel stereo output topologies

Applications

• High-power home theater systems
• Professional audio amplifiers
• Active loudspeaker enclosures

Procurement Notes

Verify the exact suffix 'ADDVR' against the datasheet to confirm the specific tape-and-reel packaging and lead-free status. Confirm RoHS3 compliance requirements match your assembly process. Check for the Not Recommended for New Design (NRND) status if planning long-term production. Ensure the 44-pin HTSSOP footprint matches your PCB layout constraints.

Selection Notes

Select this component when a digital interface is required rather than analog inputs. Compare power delivery capabilities against load impedance requirements, specifically noting the difference between 2-ohm and 4-ohm performance. Evaluate the 44-pin package size relative to available board space. Consider the NRND status for future-proofing compared to newer alternatives in the family.

Part Context

This part belongs to the TAS5342L series of high-efficiency digital audio amplifiers from Texas Instruments. It is designed for applications requiring high power density and low distortion. The device utilizes digital pulse-width modulation technology to drive speakers directly, reducing external component count compared to traditional linear amplifiers.

Replacement Considerations
