MONAURAL 4.5W Non-Clip DIGITAL AUDIO POWER AMPLIFIER
General Description
NS4158 is a class D can switch work mode, with the function of preventing distortion, low EMI, no filter,
5 w high efficiency mono audio power amplifier. class D work mode can be controlled through a terminal high
and low level switch, to match different application environment. Its unique prevent distortion function can
effectively prevent the input signal overload, battery voltage drop caused by the output signal distortion, can
effectively protect the power output at the same time the speaker is not damaged. The actual application can be
set by software line pulse amplifier working in preventing distortion mode and normal mode. Even in class D
work mode, NS4158 adopts advanced technology, within the scope of the whole bandwidth greatly reduces the
EMI interference, minimize impact on the rest of the parts. The output PWM modulation structure without filter
and feedback resistance built-in way to reduce the external components and PCB area and system cost. When
the NS4158 working in voltage of 5 v, it can provide up to 45.5W for 2 load output power.
NS4158 built-in over-current protection, overheating protection and under-voltage protection, effectively
protect the chip under abnormal working conditions are not damaged. And using spread spectrum technology
fully optimize a new circuit design, the efficiency of more than 85% is more suitable for low voltage, high
power output audio system.
NS4158 provide SOP8 encapsulation, rated operating temperature range for - 40 to 85 .
