What is IC 358?

The LM358 IC is a great, low power and easy to use dual channel op-amp IC. It is designed and introduced by national semiconductor. It consists of two internally frequency compensated, high gain, independent op-amps. This IC is designed for specially to operate from a single power supply over a wide range of voltages.

What is the function of IC LM358?

LM358 is the main controller that controls the whole system. Here its works as a voltage comparator, the output of the voltage comparator will be High when the voltage at the non-inverting input terminal (+) is greater than the voltage at the inverting input terminal (-).

How many comparators does LM358?

2 comparator
Robo India in this tutorial explains how to use Operational Amplifier (Op Amp) as comparator. In this tutorial LM358 IC is used. It has got 2 comparator.

How op amps are used as a buffer?

An op-amp can be configured as a voltage buffer by: Connecting the input signal to the non-inverting (+) input, and. Connecting the output directly back to the inverting input (-) with a wire.

What is CD4017 IC?

The CD4017 is a CMOS Decade counter IC. CD4017 is used for low range counting applications. The circuit designed by using this ic will save board space and also time required to design the circuit. CD4017 is as ‘Johnson 10 stage decade counter’.

How many pins are there in a LM358 IC?

Pin Configuration of LM358 IC The pin diagram of LM358 IC comprises of 8 pins, where Pin-1 and pin-8 are o/p of the comparator Pin-2 and pin-6 are inverting i/ps

How is ldr2 connected to LM358 IC?

Similarly, LDR2 is connected with R2 (10K) in series. The connection point of LDR2 and R2 is the Output of the LDR2, which is connected to pin 5 of the LM358 IC. Pin 5 is the non-inverting input terminal of the LM358 IC of the second operational amplifier.

What is the difference between pins 2 and 3 of IC?

Pin 2 (inverting input of IC) is connected to a potential divider R2, R3 that gives half supply voltage to pin 2. Pin 3 (None inverting input) of IC base is connected to the VCC through R1 and a Push to on switch.

Which pins are used to connect the IC base to the VCC?

Pin 3 (None inverting input) of IC base is connected to the VCC through R1 and a Push to on switch. Output pin 6 is used to connect the visual indicator LED via the current limiting resistor R4.
