LM386 Audio Amplifier Module (200 Times Gain Audio Amplifier)

From Makers Electronics's description

Description: This amplifier module is based on the LM386 operational amplifier which is a high-gain, frequency compensated operational amplifier designed to operate from a single power supply over a wide range of voltages. It is used in conventional operational amplifier circuits that need to be operated from a single power rail. Features On-board LM386 Chip Gain= 200. On-board speaker wiring block. On-board 10K variable resistor, you can adjust the volume with it. On-board power indicator. The chip pin leads, can be directly input audio signal Operating voltage: 5 ~ 12V Size:41 x14 mm Wiring Label Meaning Connection VCC Power source Connect to 5 – 12V source IN Input audio signal Connect to your Audio signal GND Ground Connect to GND or negative terminal of power GND Ground Connect to GND or negative terminal of power OUT Output (Terminal) Connect to speaker positive terminal GND Ground (Terminal) Connect to speaker negative terminal Documents LM386 Datasheet
