Working Principles

The CGD985LCU is an operational amplifier that amplifies small input signals to a higher output voltage. It operates based on the principles of differential amplification and feedback. The non-inverting input receives the input signal, while the inverting input provides a reference voltage. The amplifier amplifies the difference between these two inputs and produces an amplified output signal. The gain and characteristics of the amplifier can be adjusted using external components connected to the compensation and offset null pins.
