Working Principles

The EL7156CSZ is an integrated circuit designed to amplify and condition electrical signals. It operates by receiving input signals through the inverting (-) and non-inverting (+) inputs. The internal circuitry amplifies the input signal and provides a rail-to-rail output swing, ensuring maximum utilization of the supply voltage range.

The IC is powered by a positive supply voltage (V+) and a negative supply voltage (V-). The enable/disable pin (ENBL) allows the user to control the power consumption of the device. When enabled, the IC operates according to its specifications. When disabled, the IC enters a low-power state, reducing current consumption.
