Working Principle

The ADS62P28IRGCR utilizes an 8-bit successive-approximation converter architecture for data acquisition. This architecture works by starting with the most-significant bit (MSB) and then successively approximating the remaining bits to generate a digital representation of the analog input. This allows the ADC to have a low power consumption and high accuracy.

In addition, the ADS62P28IRGCR also features a classical three-stage design with a fully differential pipeline analog-to-digital converter, wideband reference buffer, and output gain and stage. Its wideband reference buffer allows for a self-calibrating architecture, resulting in reduced jitter and improved performance. Furthermore, the output gain and stage provides linearity correction and adjustable gain, allowing for an optimized performance based on the application’s requirements.

Features

The ADS62P28IRGCR features a wide input dynamic range and excellent signal-to-noise ratio. It has a maximum input range of 2.75V and a differential linearity performance of ±1.25mV, making it ideal for applications that require accurate, low-noise results. Furthermore, it features a high-speed, low latency sampling rate of up to 1.25GHz, with a maximum sampling rate of 3GHz. This makes the ADC well-suited for applications that require fast data acquisition.

The ADS62P28IRGCR also comes with a high-precision analog-to-digital converter clock, which allows for an adjustable sampling rate for precise timing control. Additionally, the clock can be disabled for a low power state operation and also supports an external clock source for synchronization. Furthermore, integrated power and noise cancellation functions ensure accurate results and help reduce the number of external components required.

In addition, the ADS62P28IRGCR comes with multiple features to facilitate high-speed data communications. It features two high-speed LVDS channels, which support up to 500Mbps data rate. Furthermore, it supports both 26LVDS and 32LVDS LVDS connections, allowing for simple and efficient data transfer. Additionally, the integrated PLL allows for synchronization with the MCU, decreasing the latency of the data communications.

The ADS62P28IRGCR also features an integrated temperature sensor, which helps in temperature monitoring and control. The ADC is also equipped with integrated memory to store one’s settings and a calibration transfer function, which helps to reduce non-linearity errors. Last but not least, the integrated high-precision, low-noise reference voltage ensures excellent ADC performance.

In summary, the ADS62P28IRGCR from Texas Instruments is an ideal solution for high-speed, high-accuracy data acquisition because of its low latency and high throughput performance and its versatile architecture. Due to its high-precision, low-noise design, the ADS62P28IRGCR is well-controlled for applications that require precision, such as in industrial automation, life sciences, and healthcare. The ADC is also well-suited for applications that require fast data acquisition, such as beamforming and ultrasound imaging. Overall, the ADS62P28IRGCR offers an excellent solution for a wide range of data acquisition applications.
