HDM16416L-1-L30S Hantronix LCD Character Display Modules & Accessories Yellow Transflective Yellow LED Backlight datasheet, inventory & pricing. The LM386 is a power amplifier designed for use in low volt-. age consumer applications. The gain is internally set to 20 to. keep external part count low, but the addition of an external. resistor and capacitor between pins 1 and 8 will increase the. gain to any value up to 200. The LM386 is an integrated circuit containing a low voltage audio power amplifier. It is suitable for battery-powered devices such as radios, guitar amplifiers, and hobby electronics projects. The IC consists of an 8 pin dual in-line package ( DIP-8 ) and can output 0.25 to 1 watts of power depending on the model using a 9-volt power supply.
