Product Introduction

Overview

The TPA3112D1PWP is a 25-W efficient, Class-D audio power amplifier designed by Texas Instruments. This component is optimized for driving bridge-tied speakers and features advanced EMI Suppression Technology, allowing the use of inexpensive ferrite bead filters at the outputs while meeting EMC requirements. The amplifier includes the SpeakerGuard™ speaker protection system, which comprises an adjustable power limiter and a DC detection circuit to ensure robust speaker protection. With its high efficiency of over 90%, the TPA3112D1PWP eliminates the need for an external heat sink during music playback.
