Application Field

The EL5811IREZ is an excellent choice for high‑precision industrial applications, such as: real‑time data acquisition systems, closed‑loop control systems, sound and vibration detection systems, temperature measurement systems, and transducer–sensor conditioning and applications. This amplifier can also be used for light measurement, motion detection, and air-flow control, and for noise measurement.

Working Principle

The EL5811IREZ works on the principle of voltage feedback, and is made up of a differential pair of NPN transistors. Each of these behaves as a differential input amplifier. The pair of NPN transistors amplifies the difference between the two input signals and drives the output transistors. This increase in the DC current at the output terminals of the NPN transistors helps to improve the gain of the amplifier, and helps to reduce the distortion in the output signal. The output of the differential pair is then connected to a common base NPN transistor, which acts as an additional amplifier.

The EL5811IREZ also provides a wide common mode input range, which allows it to operate with a wide variety of input voltages. The wide common mode input range makes the EL5811IREZ ideal for high-precision, low‑impedance applications, such as measurement, sensor conditioning and closed loop control.

The EL5811IREZ features high output current capability, fast settling time and low noise. This makes it ideal for applications requiring fast response times. In addition, the EL5811IREZ is stable under a wide range of conditions, and can be used with a wide range of power supplies, including both single‑ended and double‑ended supplies.

The EL5811IREZ also provides excellent common mode rejection ratio, which helps to reduce the amount of noise in the output signal. This amplifier is suitable for both single and multiple-channel applications, and can be used with a wide range of gain settings.
