Working Principles

The EL5724IREZ is an operational amplifier designed to amplify and condition electrical signals. It operates by receiving input signals through its differential inputs (IN1, IN2, IN3, IN4) and amplifying them with high gain. The amplified signals are then processed and conditioned internally using the built-in voltage reference (VREF). The resulting output signals (OUT1, OUT2) have low noise and a wide bandwidth, making them suitable for various applications.
