The AD2S90AP is a signal conditioning device from Analog Devices that is designed to convert a continuous analog input signal into a low-resolution representation of the signal. It can be used in a variety of applications and environments, including automotive, industrial, and medical applications. To learn more about the application field and working principle of this device, read on.

Application Field: The AD2S90AP is a powerful IC that is suitable for a range of data acquisition applications. It can be used to measure analog signals from a variety of sources, such as accelerometers, strain gauges, and potentiometric networks. Additionally, it can be used to measure velocity and position signals in motors, as well as in robot navigation applications. This device can also be used in precise and reliable feedback control algorithms, making it suitable for implementing cost-effective, high-performance motion control systems.

Working Principle: The AD2S90AP is based on a circuit known as the Delta-Sigma A/D converter, which is a derivative of the Delta-Sigma Modulator. The modulator converts an input analog signal into a digital signal by counting the number of times the signal crosses certain predefined threshold levels. The output of the modulator is then sampled by a Digital Signal Processor (DSP). The DSP then quantizes the samples into a low-resolution digital output signal. The AD2S90AP uses this technique to generate a nonlinear, low-resolution representation of the input analog signal, which can then be used for a variety of data acquisition applications.

Conclusion: The AD2S90AP is a powerful signal conditioning device from Analog Devices that is specifically designed for data acquisition applications. It works by converting an input analog signal into a low-resolution representation of the signal, using the Delta-Sigma A/D converter circuit. This device can be used in a range of applications, including automotive, industrial, medical, and motion control systems, enabling cost-effective, high-performance operation in any environment.
