Working Principles

The AD626AR is an operational amplifier that amplifies analog signals with high precision. It utilizes a differential input stage to amplify the voltage difference between the IN+ and IN- pins. The amplified signal is then further processed and amplified by subsequent stages within the IC. The output voltage is proportional to the difference between the voltages at the IN+ and IN- pins, multiplied by the gain of the amplifier.
