Working Principles

The QT301-D is an operational amplifier that amplifies and conditions input signals. 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 amplified output is then fed back to the inverting input through a feedback network, which helps control the gain and stability of the amplifier.
