Working Principle

The working principle of ICL7621BCSA is based on the basic amplifier circuit principles. The amplifier works based on the differential amplifier circuit configurations. ICL7621BCSA uses a differential amplifier configuration to allow the output signal to be produced from the difference between the two input signals. The circuit also includes a voltage gain stage to increase the gain of the output signal.

The output signal from the differential amplifier is then passed to the voltage regulator. The voltage regulator provides a steady output voltage signal by adjusting the voltage gain and the offset voltage of the amplifier. Finally, the signal is passed to the offset electronics which nullify the offset voltage errors of the signal.
