The HJ386 audio power amplifier is mainly used in low-voltage consumer products. To minimize external components, the voltage gain is built-in at 20. However, by adding an external resistor and capacitor between pin 1 and pin 8, the voltage gain can be adjusted to any value up to 200. The input terminal is referenced to ground, while the output terminal is automatically biased to half of the supply voltage. At a supply voltage of 6V, its static power consumption is only 24mW, making the HJ386 particularly suitable for battery-powered applications. It is widely used in AM/FM radio audio amplifiers, hands-free telephone speaker systems, small servo drivers, portable tape recorder audio power amplifiers, television audio systems, ultrasonic drivers, power converters, and more. It can replace the LM386 and this product has achieved full localization.
The characteristics of the device are as follows:Low static power consumption, about 4mA, can be powered by batteries.Voltage gain adjustable from 20 to 200.Wide power supply voltage range, Vcc=4 to 12V.Few external components.Low distortion.
