Data acquisition involves converting physical signals such as temperature, acceleration, and pressure into digital representations that can be read and manipulated by computers. The process of transforming analog signals into digital signals is known as analog-to-digital conversion. In this article, we will discuss the application field and working principle of ADS805E/1K, an analog-to-digital converter designed for data acquisition in precision environments.

Formally called an integrated circuit (IC) solution, the ADS805E/1K is a single-package discrete-time sigma-delta converter catering to high-resolution measurement applications. This device provides accuracy and precision, as well as low cost and high dynamic range when compared to conventional analog-to-digital converters (ADCs) and mixed-signal digital-analog converters (DACs). Key applications for this device include vehicle instrumentation, consumer devices, medical equipment, industrial automation, communications, and consumer electronics.

In terms of the working principle, the ADS805E/1K has a simple design that contains many of the fundamental components of analog-to-digital conversion. The device performs single-ended analog-to-digital conversion using a sigma-delta modulation technique. An on-chip digital low-pass filter follows the modulator to remove high-frequency artifacts. The modulator and filter are both clocked with a single master clock, thus simplifying timing considerations.

The key features of the ADS805E/1K include an integrated low-pass filter, single-ended analog input, and a high input impedance. The input voltage range is also adjustable, allowing for a wide range of signal types and levels to be accurately converted. The device also has a temperature range of 0°C to +85°C, which enables it to be used in commercial and industrial applications with wide ranges of operating temperatures. Furthermore, the device has a low-power consumption, which makes it suitable for battery-powered applications that require minimal energy expenditure.

Performance-wise, the ADS805E/1K offers a resolution of up to 1Kbits/s, allowing for high-precision, high-resolution data acquisition. The device also has a maximum operating frequency of 20kHz, allowing for capture of fast-changing signals. Furthermore, the device has a low-noise capability, meaning that it can achieve a high signal-to-noise ratio with minimal interference from external noise sources. Overall, the device provides excellent signal-to-noise performance and low-power consumption, making it ideal for low-power precision applications.

In conclusion, the ADS805E/1K delivers precision data acquisition performance in challenging environments. It provides high resolution and low noise, plus it has a wide temperature range and low power-consumption for battery-powered applications. With its single-ended analog input, adjustable input voltage ranges, and integrated low-pass filter, the ADS805E/1K is an excellent choice for precision data acquisition.
