NSIWAY NS4110B Ultra Low EMI, Differential Input, 20W Single-Channel AB/D Class Audio Power Amplifier
Update: 27 October, 2023
NS4110B is a differential input, ultra low EMI, no-filter, 20W single-channel ABD class audio power amplifier. It can be controlled by different levels to control the chip working mode: when the CTRL pin voltage is above 2.0V, the chip enters the D class working mode, 0.9-1.6V when the chip enters the AB class working mode, 0.5V below the chip is turned off, the application is flexible and convenient. NS4110B adopts advanced technology, which greatly reduces EMI interference in the whole bandwidth range and minimizes the impact on other external components. Its output no-filter PWM modulation structure reduces external components, PCB area and system cost. NS4110B can provide up to 18W of output power to 4Ω load at a working voltage of 12V, and its efficiency of more than 90% is more suitable for portable audio systems. NS4110B has built-in overcurrent protection, overheating protection and undervoltage protection functions to effectively protect the chip from being damaged in abnormal working conditions. NS4110B is available in eSOP-8 package with an operating temperature range of -40℃ to 85℃.
