Data Acquisition - Analog to Digital Converters (ADC) is a technology that enables digital devices to understand analog signals. The ADS4128IRGZ25 from Texas Instruments is a high-speed, 16-bit simultaneous sampling ADC with serial LVDS outputs which makes this device a great choice for applications such as data acquisition, audio/video conversion, instrumentation and communication. This article will discuss the application field, features and working principle of this particular device.

Application field

The ADS4128IRGZ25 is specifically designed for applications that require high accuracy with low power consumption. This device is ideal for use in high speed data acquisition, audio/video conversion, instrumentation and communication. It is highly suitable for medical imaging, scientific and industrial process control, communications systems, as it is able to accurately detect signals with very low power consumption. Additionally, it can also be used in radar and sonar systems, due to its high speed design. The device has a guaranteed true 16-bit resolution with no missing codes and no distortion, so it is a great choice for applications that require precise analog-to-digital conversion.

Features

The ADS4128IRGZ25 is a high speed 16-bit simultaneous sampling ADC with serial LVDS outputs. It features an on-chip sample-and-hold stage, as well as a high speed clock generator, with a maximum sampling rate of 250MHz. The device has a guaranteed true 16-bit resolution with no missing codes and no distortion. Additionally, it features excellent power dissipation and power efficiency, with a typical power dissipation of < 0.4mW per channel. This makes the device well suited for battery-powered applications. It also features an integrated temperature sensor, which allows for in situ self-calibration.

Working principle

The working principle of the ADS4128IRGZ25 is based on the principle of analog-to-digital conversion. The device converts analog input signals into digital data representation. This is accomplished through the use of two primary components: the sample-and-hold circuit and the ADC core. The sample-and-hold circuit is responsible for capturing and storing an instantaneous value of the analog input signal. This value is then converted into digital data by the ADC core, which performs the necessary calculations and manipulations to accurately determine the digital representation of the input signal. The serial LVDS outputs allow for the digital data to be output for further processing or analysis.

In summary, the ADS4128IRGZ25 from Texas Instruments is a high-speed, 16-bit simultaneous sampling ADC with serial LVDS outputs. This device is well suited for applications that require high accuracy with low power consumption, such as medical imaging, scientific and industrial process control, and communication systems. It features a guaranteed true 16-bit resolution with no missing codes and no distortion, and its low power consumption enables it to be used for battery-powered applications. Its working principle is based on the principle of analog-to-digital conversion, whereby the sample-and-hold circuit is used to capture and store an instantaneous value of the input signal, and the ADC core is used to convert this value into a digital data representation. The serial LVDS outputs allow for the digital data to be output for further processing or analysis.
