Linear amplifiers, such as the OP285GS-REEL, provide great versatility and can be used in a wide range of applications in instrumentation, from basic voltage monitoring to more advanced applications, such as saturating and limiting signals. The OP285GS-REEL instrumentation amplifier is a precision, monolithic integrated amplifier designed for high performance, low noise, and high linearity.

Typical Applications of the OP285GS-REEL

The OP285GS-REEL amplifier is frequently used in a variety of instrumentation and measurement applications, such as audio, video, and test and control systems. The precision characteristics of the amplifier make it particularly suitable for use in precision level sensing and dynamic range limitation. It is often used in audio and video systems to achieve high resolution with low noise, and in test and control systems to provide precise and accurate measurements. Other applications include power supplies, data acquisition systems, and high fidelity audio systems.

Working Principle of the OP285GS-REEL

The OP285GS-REEL instrumentation amplifier is based on an internally-compensated, three-stage, differential input configuration. This configuration provides improved common-mode and offset voltage rejection, as well as low noise and high linearity, making it highly suitable for precision level sensing and dynamic range limitation. The amplifier produces voltage gain via the feedback loop between the closed-loop gain and the output voltage. This feedback loop controls the output voltage, and therefore, the gain of the amplifier. The output voltage is also proportional to the input voltage, since the amplifier is voltage operated. By varying the feedback, an adjustable gain is achieved, thus producing different levels of amplification.

The OP285GS-REEL amplifier additionally features a power supply rejection ratio of more than 70 dB, and a wide supply voltage range from 4 V to ±20 V. This allows the amplifier to operate with a wide range of power supply voltages, thus providing longer product life, increased reliability, and increased cost savings. Furthermore, the miniature size of the OP285GS-REEL allows for easy installation, thereby saving on cost and time.
