The AD538SD/883B are linear-analog multipliers, also known as phase sensitive rectifiers, which contain a phase sensitive rectifier circuit and a 50 ohm resistor allowing amplification of small signals. These devices are used in a wide variety of applications, including control and automotive systems. In short, they are used to provide a high level of gain control, since they are designed to have a highly variable input and output gain.

The working principle behind these devices is fairly simple. They contain a diode in the circuit, which is responsible for rectifying the input signal and for producing the amplified output. Additionally, a resistor is connected in series with the diode, which serves to limit the output current, as well as the gain control. Depending on the model, the resistor is adjustable, or preset to a specific value. The input and output of the devices are then connected to the appropriate inputs and outputs on the application system.

The AD538SD/883B multipliers typically offer a wide range of gains and can be used in a variety of applications. These devices are often used in automotive applications such as engine control, engine sound level control, and powertrain control. They can also be used in audio applications, where they can be used to increase or decrease the overall gain of an audio system. Additionally, they can be used in communication systems, such as cellular phones, to control the gain of the transmitted signal.

The AD538SD/883B devices can also be used in various data acquisition systems. By connecting the output of the device to a digital input on the data acquisition system, it is possible to measure the gain of the system. This can then be used to provide feedback to the application system so that the system can determine the optimal gain setting for the application.

The AD538SD/883B can also be used in industrial automation applications, where they can be used to control the speed and direction of a motor. This is done by connecting the output of the device to the motor controller, and then setting the reference input to the desired motor speed. The motor will then be driven by the output of the device, and will be able to stop at the appropriate speed and direction thanks to the gain control provided by the device.

The AD538SD/883B is also widely used in the medical industry, where they are often used to control the power output of a machine, such as a heart monitor. By connecting the output of the device to the power output of the machine, the doctor can control the power output of the machine, while also providing feedback to the machine so that it can adjust the output to the desired levels.

The AD538SD/883B are versatile analog multipliers, dividers, and phase sensitive rectifiers which provide a high amount of gain control and flexibility for numerous applications. By connecting the devices to the appropriate inputs and outputs on an application system, they can be used to provide a wide range of gains and to control the output of the system. This makes them ideal for use in a wide variety of applications, and is why they are so widely used.
