Introduction

AI Translation

The TS4990 is designed for demanding audio applications such as mobile phones to reduce the number of external components. This audio power amplifier is capable of delivering 1.2 W of continuous RMS output power into an 8 Ω load at 5 V. An externally controlled standby mode reduces the supply current to less than 10 nA. It also includes an internal thermal shutdown protection. The unity-gain stable amplifier can be configured by external gain setting resistors.

Features
