NS4196 Description:
    The NS4196 is a Class AB/D dual-mode, anti-distortion, digital volume control, 5W mono audio amplifier.
    Class AB/D dual operating mode can be controlled separately by high and low levels. The AB/D class switching function combines the advantages of the AB class power amplifier and the D class power amplifier, making the FM completely free from interference, and achieving high efficiency when playing music. The unique anti-distortion (NCN) function can dynamically adjust the system gain by detecting the distortion of the output signal, which not only effectively prevents the damage of the overload output to the speaker, but also brings a comfortable hearing experience.
    In addition, it is also possible to control the AB/D class working mode switch with only one pin through the way of a single pulse, the anti-distortion (NCN) function is opened and closed, and the power amplifier is opened and closed (shutdown), the application is simple.
    The NS4196 integrates digital volume control. The volume can be controlled with two buttons. Control range from -34dB to 22dB.
    NS4196 built-in over current protection, over temperature protection and under voltage protection functions, effectively protect the chip from being damaged under abnormal working conditions.
    The NS4196 delivers 5W of output power at 5V power with a driven 2Ω load. With an efficiency of more than 90% in Class D mode and flexible application, the NS4196 is ideal for portable audio products.
    The NS4196 is available in a SOP16 package with a rated operating temperature range of -40 ° C to 85 ° C.
