Product Introduction

Overview

The TS482IST, produced by STMicroelectronics, is a dual audio power amplifier designed to drive 16 or 32Ω stereo headsets efficiently, even at low voltages. It delivers up to 100mW per channel into 16Ω loads with a total harmonic distortion plus noise (THD+N) of 0.1% from a 5V power supply. The amplifier is unity-gain stable and can be configured using external gain-setting resistors. It is available in MiniSO-8 packaging, making it suitable for compact audio applications.
