TAS5342DDVR

Overview

The TAS5342DDVR is a high-performance stereo digital amplifier power stage from Texas Instruments, housed in a thermally enhanced 44-pin HTSSOP package. It delivers up to 100 W per channel into a 4-ohm bridge-tied load (BTL) at 10% THD+N. The device supports single-ended and parallel bridge-tied load configurations with corresponding power outputs of 40 W into 4 ohms and 200 W into 2 ohms respectively. Operating parameters include a GVDD supply range of 10.8 V to 13.2 V and an operating temperature range of 0°C to 70°C.

Feature Summary

• Integrates comprehensive on-chip protection systems including short-circuit, over-current, under-voltage, over-temperature, and PWM activity detection.
• Features a PurePath Digital interface designed for low harmonic distortion and low idle current operation.
• Includes a power-on-reset circuit to eliminate the need for complex power-supply sequencing.

Applications

• Mini audio systems
• Micro audio systems
• DVD receivers
• Home theater systems

Procurement Notes

Verify component authenticity through authorized channels as this part is marked Not Recommended for New Designs. Confirm package integrity upon receipt due to moisture sensitivity requirements. Ensure proper ESD handling protocols are followed during storage and installation to prevent damage to internal MOS gates.

Selection Notes

Select this component for applications requiring high-power stereo output with integrated digital control. Evaluate thermal management needs carefully given the power dissipation characteristics. Ensure compatibility with the required PWM frame rates and verify that the system design meets the recommended decoupling and filtering guidelines for optimal performance.

Part Context

This device belongs to the TAS5342 family of digital amplifier power stages. It is designed to work in conjunction with Texas Instruments PWM processors like the TAS5518. The DDV suffix specifically denotes the 44-pin HTSSOP PowerPad package which facilitates efficient heat transfer to a heatsink.
