Introduction

The AD7863ARSZ-2 is an integrated circuitseries of Analog-to-Digital Converters (ADC) produced by Analog Devices Inc. It is designed as an economical, high-performance ADC for fast data conversion. It is part of a larger portfolio of Analog-to-Digital Converters (ADC) products being offered to the market by Analog Devices.

Application Field

The AD7863ARSZ-2 is a very versatile ADC, and it is widely used in applications such as industrial process control systems, automotive and aerospace applications, medical systems, instrumentation, and other applications requiring high accuracy and low system power consumption. It is also suited for portable devices, as it is both lightweight and low power. It is a great choice for applications in which fast system power up time is desired, as it is a highly efficient device that can simultaneously sample multiple signals and convert them quickly.

Working Principle

The AD7863ARSZ-2 operates on a single supply of 3.3V to 5.5V and hence provides very low power dissipation. The AD7863ARSZ-2 uses a charge transfer technique based on the leakage capacitance reset principle. It is a two-step ADC, with a preamplifier stage and successive approximation register (SAR). During the first step, the preamplifier increases the input signal and adjusts the offset. Then, an internal sample-and-hold and charge balancing capacitor are used to convert the input signal from analog to digital. The SAR then converts the digital information into a parallel format.

The AD7863ARSZ-2 includes a power-down feature that allows the user to reduce power consumption to the minimum and is especially useful in portable and battery-powered systems. The device also offers an internal reference and a programmable gain amplifier that enables the input signal to be scaled and adjusted before conversion, saving the user the time and space associated with external reference circuits and amplifiers. Additionally, the device provides an internal/external conversion timing control that allows the user to control the conversion speed, and it also includes an analog output buffer that is useful for testing and debugging.

Conclusion

The AD7863ARSZ-2 ADC from Analog Devices is a high-performance, low-power solution for fast data conversion. Its features, such as the power-down, internal reference, and programmable gain amplifier make it a great choice for a variety of applications, e.g., in industrial process control systems, automotive and aerospace applications, medical systems, etc. The internal/external conversion timing control further enables the user to control the speed of conversion. Finally, the analog output buffer feature is useful for when the user needs to test or debug the system.
