Analog to Digital Converters (ADCs) are essential elements of countless electronics systems. These converters take analog signals and convert them into a digital form for further processing. The ADS5287IRGCT is a high speed 20 bit, dual channel, SAR ADC from Texas Instruments which operates from a wide supply range and offers a great mix of features. This article will discuss the application field and working principle of the ADS5287IRGCT.

In industrial and automotive applications, the need for accurate signal conversion is critical. The ADS5287IRGCT ADC is the perfect choice for such applications. It features an impressive +/-1LSB DNL and +/-0.6LSB INL accuracy with a wide range of input signals up to 2.8Vpp. This converter can sample at speeds up to 800MSPS per channel, making it capable of converting data with high accuracy and high throughput. In addition, its high-impedance inputs make it suitable for operation in difficult signal environments, such as automotive, robotics and medical applications.

The ADS5287IRGCT ADC is based on the Successive Approximation Register (SAR) architecture. SAR ADCs are over-sampled converters which employ a sensing technique, referred to as charge redistribution. Using this technique, the difference between the input signal and a reference voltage is detected and then amplified internally. The amplified signal is then used to resize a reference voltage which is then compared against the input signal. This process is repeated until the difference between the input signal and reference voltage is minimal and hence, the information related to the input signal is obtained.

The ADS5287IRGCT offers a wide variety of features that are beneficial to the user. It supports an adjustable output data rate from 100MSPS up to 800MSPS per channel, independent input offset and gain error compensation, a flexible and programmable reference voltage, built-in timing and synchronization capabilities, and low power consumption. Furthermore, its auto blanking feature offers a sleep mode to extend battery life in portable applications.

The ADS5287IRGCT ADC is an ideal choice for high-precision data acquisition applications in industrial and automotive settings. Its high accuracy and high speed provide the user with an accurate conversion of signals which can be used for further processing. Furthermore, its features provide the user with great flexibility and ease of use. With its wide range of features, the ADS5287IRGCT is the perfect choice for high speed, high accuracy ADC conversion.
