In this blog you can find opamp tutorial and circuits like differentiator integrator, summing amplifier and many more circuit. Operational amplifier basics detailed explanation and working of each circuit.

An operational amplifier is a DC-coupled high-gain electronic voltage amplifier amplifier that has high gain, differential input, high input resistance, and low output resistance.

There are mainly two types of opams amplifiers inverting amplifiers and others one is non inverting amplifier.

Automatic Night Lamp Circuit Diagram using LDR and LM358 OPAMP

This article explains an automatic night lamp circuit diagram using LDR and LM358 OPAMP which automatically turns the LEDs ON at night and OFF when it is daytime. The sensing part which is being used for detecting the light is a Light Dependent Resistor (LDR). The resistance of LDR depends on the light incident on […]

Schmitt Trigger Circuit Working and Applications

A Schmitt Trigger circuit is a comparator circuit with some modifications. As compared to a normal comparator circuit the Schmitt trigger circuit has a hysteresis curve. This means that it has two threshold voltages an upper threshold and a lower threshold voltage. In Schmitt trigger circuit hysteresis is created by applying positive feedback to the non-inverting […]
