Product Introduction

Overview

The TPA1517DWPRG4 is a stereo audio power amplifier produced by Texas Instruments. This component is designed to deliver high-quality audio output and is particularly suited for applications requiring robust and efficient audio amplification. The TPA1517 contains two identical amplifiers, each capable of delivering 6 W of continuous average power into a 4-Ω load at 10% THD+N or 5 W per channel at 1% THD+N. The amplifier features a fixed gain of 20 dB and includes thermal protection, mute, and standby functions, making it versatile for various power-sensitive applications.
