AD9824KCPZRL Application Field and Working Principle

Introduction

The AD9824KCPZRL is a high-performance analog-to-digital converter (ADC) designed for interfacing to sensor and detector interfaces. The device provides high speed and precision digital conversion of analog signals such as voltage, current and temperature. The device features an integrated input multiplexer, sample-and-hold amplifier, 8-bit and 10-bit resolution and a low-pass Digital Filter.

Application Field

The AD9824KCPZRL is a relatively flexible and multipurpose ADC which makes it suitable for a variety of applications. Its small size and low-power consumption allows it to be integrated in a variety of sensor, detector, and signal-conditioning systems. It is also suitable for general-purpose signal conditioning applications such as audio signal-to-digital converters and pressure controllers.The AD9824KCPZRL is an ideal device for interfacing to industrial process control applications such as process temperature, pressure, and flow control systems, as well as precision control systems for medical and laboratory devices. Furthermore, the device is designed for use in automotive applications where it can be used for controlling engine monitoring, emissions control, and other environmental sensors.

Working Principle

The AD9824KCPZRL is a dynamic ADC which utilises a successive-approximation tracking architecture. The device operates in a single conversion mode and converts the input signal at a sample rate of up to 100 MHz.The device starts each conversion process by acquiring the input signal and holding it in a sample-and-hold amplifier which is connected to an 8-bit- and 10-bit-resolution successive-approximation register (SAR). The SAR makes a series of approximation cycles for the conversion, whereby each cycle is compared to a reference voltage using a comparator. The result of the comparison is used to adjust the output of the SAR resulting in the device’s digital output.The device can be configured with several mode settings that enable the user to optimise the performance of the ADC according to the specific application. The device has an integrated low-pass digital filter (LDF) which helps to reduce noise and improve signal to noise ratio. The device also has an offset adjustment which allows the user to adjust the output of the ADC for improved linearity.

Conclusion

The AD9824KCPZRL is a high-performance analog-to-digital converter designed for sensor and detector interfaces. The device integrates an input multiplexer, 8-bit and 10-bit resolution, and a low-pass digital filter providing an optimal solution for a variety of sensor-based applications. The AD9824KCPZRL is suitable for industrial process control, automotive control, audio signal-to-digital conversion, and medical and laboratory applications. The device operates in a single conversion mode and employs a successive-approximation tracking architecture. It is also configurable with several mode settings which allow the user to optimise the performance of the ADC according to the specific application.
