Data Acquisition – Analog to Digital Converters (ADC) is an important component in digital systems. It is responsible for converting the analog signal into digital signal, allowing the processor to analyze and make decisions based on the signal received. AD7921AUJZ-R2 is one of the commonly used ADC devices in the market. This article aims to examine the application fields and working principle of AD7921AUJZ-R2.

AD7291AUJZ-R2 (AD7908LJZ-R2) is a 12-bit, 1-channel/2-channel (dual) Successive Approximation Register (SAR) ADC. It uses a unique mixing signal suppression technology to control signal clock jitter and guarantees improved performance of the analog signal pre-amplifier low-pass filter. Its 12-bit resolution signal is capable of providing 0.25mV accuracy over a wide range of signal parameters such as signal amplitude, temperature, frequency, and capacitance. Moreover, the AD7291AUJZ-R2 is designed with a low-power consuming feature, allowing it to achieve only 1.2mW of power in a nominal 3.3V power supply.

AD7291AUJZ-R2 is used in a wide range of application fields such as industrial process control, automotive telematics, frequency modulation (FM) radio, motion detectors, and health monitoring. In industrial process control applications, the ADC is used for monitoring and controlling the system’s various parameters such as temperature, pressure, and flow. In health monitoring applications, the ADC is used for monitoring the pulse rate and respiration rate of patients in hospitals. The ADC also has applications in automotive telematics and frequency modulation (FM) radio. Furthermore, the ADC can be used in the motion detector application to detect any movements and alert the associated security device.

The working principle of AD7291AUJZ-R2 can be divided into two parts: analog-to-digital conversion (ADC) and digital-to-analog conversion (DAC). In the ADC portion, the analog signal is converted into a digital representation using a successive approximation register (SAR) topology. This SAR topology requires the presence of a high-performance reference generator in order to ensure accuracy and reliability of the digital output. In the DAC portion, the digital representation is converted back into an analog signal, which can then be used for any application that requires an analog signal.

In summary, AD7921AUJZ-R2 is a popular ADC device used for converting analog signals into digital signals for various applications such as industrial process control, automotive telematics, frequency modulation (FM) radio, motion detectors, and health monitoring. The working principle of this device is based on successive approximation register (SAR) topology which requires the presence of a high-performance reference generator. With its low-power consumption and wide range of applications, AD7291AUJZ-R2 is an ideal choice for many projects.
