LM358 Amplifier Module

• LM358 Operational Amplifier or Comparator IC
• LM358 High Gain Operational Amplifier Module is based on the LM358 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.
• It contains a built-in LED power indicator and a 10K adjustable resistor for gain adjustment.
• The LM358 operational amplifier module comes in handy for projects that require simple waveform amplification, such as amplifying a microphone signal. In terms of simple amplification jobs involving moderate frequency signals, such as microphone inputs, these assemblies perform pretty well. We were able to change the output over the entire range of 10mV to 1V without noticeably introducing distortion when using a 10mV 1KHz input. Since the LED has a 1K current-limiting resistor and the LM358 can withstand voltages of up to 32V, the LED will be powered at its maximum current of 20mA at roughly 22V. If utilizing the module at higher voltages, the LED can be deleted, or the 1K resistor at R10 can be upgraded to 2.2K or 4.7K.
• Use this module by applying a voltage of 5 to 12 VDC to the device’s VCC pin. Connect the sensor’s signal output to the Sig. Take the amplified output from the Sig. Out pin and connect it to the module’s input pin. The multi-turn potentiometer on the module can be used to control the gain, which has a range of 1x to 100x. Turning the pot CCW raises the amplification while doing the opposite with CW decreases it.

Applications:

• Alarm clocks, traffic lights, light intensity meters, and burglar alarm circuits are a few further uses.
