The NS4830 is a 5.3W mono Class AB/D audio power amplifier with an adaptive harge Pump boost
    The NS4830 is a Class AB/D switchable, capacitive boost type, 5.3W high efficiency mono audio amplifier. The internal gain of the chip is 24 times, which effectively reduces the number of peripheral components. Class AB/D operating mode can be switched between high and low levels through a control pin to match different application environments. Even in Class D operating mode, the NS4830 uses advanced technology to greatly reduce EMI interference over the full bandwidth range, minimizing the impact on other components. In addition, the NS4830 also has the power source adaptation ability, when the power supply is low, the power amplifier will automatically reduce the gain, thereby reducing the output power of the power amplifier.
    The NS4830 is capable of delivering up to 5.3W of output power to 4Ω loads at 4.2V operating voltage.
    The NS4830 built-in overheat protection function effectively protects the chip from being damaged under abnormal working conditions. And the use of spread spectrum technology to fully optimize the new circuit design, more than 80% efficiency is more suitable for low voltage, high power output audio system.
    The NS4830 is available in an eSOP10 package with a rated operating temperature range of -40 ° C to 85 ° C.
