Analog-to-digital converters (ADCs) are a subset of data acquisition systems that measure analog signals, such as voltage or current, and convert them into digital values. The ADC3242IRGZR is a high performance ADC for industrial applications. It features an asynchronous mixed mode readout with a 12 bit resolution and a sampling rate of 200ksps. In this article, we will explore the application field and working principle of the ADC3242IRGZR.

Application Field

The ADC3242IRGZR is a versatile ADC that is suitable for a variety of industrial, automation and testing applications. Its low-power, low-noise and high-efficiency design make it ideal for a wide range of applications, including temperature measurement, flow measurement, pressure measurement, vibration measurement and process control. Additionally, the ADC3242IRGZR can be used in medical imaging and medical electronics applications, such as in ECG, CT and MRI scanners. In these applications, it provides reliable measurements with high accuracy and low sample rate jitter.

Working Principle

The ADC3242IRGZR is a sample-and-hold, voltage-to-digital converter that works on the principle of successive approximation. First, the ADC3242IRGZR samples and holds the input voltage. Then, it compares the sampled voltage to a reference voltage and adjusts a series of switches to determine the digital output code that best approximates the input voltage. This process is repeated for each bit of resolution, so for a 12-bit converter, 12 approximation measurements are made and the resulting digital code consists of 12 bits.

The ADC3242IRGZR has an asynchronous mixed-mode readout, which allows simultaneous sampling of up to four converters. This allows for faster sampling rates and provides more flexible data acquisition than a single-channel device. Additionally, the ADC3242IRGZR features an internal digital filter and noise source cancellation, which helps reduce noise and improve accuracy of digital output readings.

Conclusion

The ADC3242IRGZR is a high performance ADC for industrial applications. It features an asynchronous mixed mode readout with a 12 bit resolution and a sampling rate of 200ksps. Its low-power, low-noise and high-efficiency design make it suitable for various industrial, automation and testing applications, as well as medical imaging and electronics. Additionally, it has an internal digital filter and noise source cancellation, which helps reduce noise and improve accuracy of digital output readings. These features make the ADC3242IRGZR a powerful and reliable tool for accurate and efficient data acquisition.
