The YD386 is a power amplifier, designed for use in low voltage consumer applications. The gain is internally set to 20 to keep the external part count low. But the additional of an external resistor and capacitor between pin 1 and pin 8 will increase the gain to any value up to 200.
* Minimum external parts;
* Wide supply voltage range: 4V~12V;
* Voltage gains:20~200;
* Ground referenced input;
* Low distortion.
