The working principle of HCPL-7800A-000E is based on the operation of an operational amplifier. An operational amplifier is an electronic amplifier with many advanced features, including high gain, low offset, low noise, and low output impedance. An operational amplifier amplifies the difference between two input signals, also known as the differential signal. This differential signal is amplified by adjusting the gain of the amplifier. The signal is then passed through an output stage, which provides the device with a single-ended or a differential output.

The HCPL-7800A-000E operates using two separate stages of amplification. The first stage consists of an operational amplifier with a gain of approximately 10,000. The two input signals are amplified by this stage and then the differential signal is passed to the second stage. The second stage amplifies the signal with a gain of approximately 100. The output of the second stage is used as the final output signal.

The HCPL-7800A-000E is a versatile and robust linear amplifier, designed for use in many instrumentation and Buffering applications.
