Working Principles

The EL7412CM is a voltage feedback amplifier that amplifies the input signal by a fixed gain. It operates by receiving an input voltage at the non-inverting input (IN+) and producing an amplified output voltage at the OUT pin. The gain of the amplifier is determined by external resistors connected to the IN+ and IN- pins. The amplifier's high-speed characteristics are achieved through its internal circuitry design and use of CMOS technology.
