OP471GS-REEL

The OP471GS-REEL is a monolithic operational amplifier from Analog Devices. It features extremely low offset voltage and wide bandwidth, making it an ideal choice for instrumentation applications. This article will discuss the application fields and working principles of the OP471GS-REEL.

Application Fields

The OP471GS-REEL is primarily designed for instrumentation applications in which very precise measurements are made. It is used in systems where the offset voltage, gain, and other parameters must be precisely controlled. This includes test and measurement applications such as process control, medical instrumentation, power supply monitoring, and data acquisition systems.

The OP471GS-REEL is also used in signal processing applications. For example, it can be used for low frequency signal measurement and recording. This device provides excellent precision and accuracy when measuring low frequency signals, allowing for good signal-to-noise ratio. It is also used in audio applications as a pre-amplifier or mixer, as it can provide very high levels of gain and precision.

Working Principle

The OP471GS-REEL is a monolithic operational amplifier, which means that all of its components are integrated onto a single chip. It consists of two main components: input and output stages. The input stage consists of two differential input pairs which are connected to two internal analog multipliers. The output stage consists of a single output. Both stages are connected to a set of external feedback components which are used to set the gain and offset of the amplifier.

The signal entering the device at the input stage is first amplified in the differential amplifier pair. This signal is then routed to the internal multipliers which are used to set the gain and offset of the amplifier. The output stage then takes the modified signal and outputs it to the external circuit. The gain and offset of the amplifier can be adjusted by changing the external feedback components.

The OP471GS-REEL is designed to provide very accurate and precise measurements, making it an excellent choice for instrumentation applications. It is capable of providing very high levels of gain and precision. With its low offset voltage and wide bandwidth, it is a great choice for measuring low frequency signals.
