![]() Working The LDR is an electronic component whose resistivity changes as light is incident on it. To understand it more clearly, let’s see the working of circuits below. ![]() Now, we can get an output from the Op-Amp. Then, we need to provide two input voltages to the Op-Amp for comparison. To use LM358 as a comparator, we need to connect the power source with the Vcc and GND pin of the LM358 IC to activate the IC. The LM358 comparator IC consists of two inbuilt operational amplifiers (Op-Amp), which means two comparators in a single IC. It has two analog input terminals, V+ and V- and one binary digital output that is low when V- is greater and high when V+ is greater. In electronics, a comparator is a device that compares two voltages or currents and outputs a digital signal indicating which is larger. The op-amp performs multiple functions based on its feedback configuration, whether resistive, capacitive, or both, and can be used as a differential amplifier, integrator, or summer. It needs to connect to the Positive(+) terminal of Supply Voltage.Īn operational amplifier, or op-amp for short, is a DC coupled high gain voltage amplifying device that is useful for signal conditioning, DC amplification, filtering, and use with external feedback components like as capacitors and resistors between its output and input terminals. ![]() ![]() It needs to connect to the Negative(-) terminal of Supply Voltage. The LM 358 has several applications, including operational amplifier (Op-amp) circuits, transducer amplifiers, DC gain blocks, comparator circuits, Active filters, current loop transmitters for 4 to 20mA and so on. ![]()
