Introduction

AI Translation

NS4111 is a 10W mono Class AB/D switching audio power amplifier with differential input, ultra-low EMI, and filterless operation. The working mode can be controlled via different logic levels, offering flexible application. Advanced technology is employed to significantly reduce EMI across the full bandwidth, minimizing interference with other external components. The filterless PWM output stage reduces external component count, PCB area, and system cost. At a supply voltage of 9V, it delivers up to 10W output power into a 4Ω load, with efficiency exceeding 90%, making it well suited for portable audio systems. Built-in overcurrent protection, thermal protection, and undervoltage protection effectively safeguard the device against damage under abnormal operating conditions. Available in an eSOP-8 package, with a rated operating temperature range of -40°C to 85°C.
