This amplifier module uses the LM358 IC operational amplifier which is a high-gain, frequency compensated operational amplifier designed to operate from a single or dual 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.
Specifications LM358 IC Adjustable gain up to 100x Non-inverting On-board 10K potentiometer for gain adjustment LED Power Indicator Input signal AC coupled to input pin by 1µF capacitor Output directly driven by IC Working Voltage Range: 5V to 12V DC Board Size: 32.7 x 13.3 mm
