Data Acquisition–Analog to Digital Converters (ADCs) provide digital signals from analog signals, allowing information that would otherwise by physically limited in analog form to be used in a digital environment. The ADS7822UB is an example of a low-power, high-speed, 10-bit ADC specifically designed to meet the requirements of applications which require data acquisitions ranging from four to ten-bits of resolution.

The ADS7822UB is a 10-bit low-power, high-speed ADC with a 2 V internal reference. It integrates two channels of analog-to-digital conversion in a single-package, using a proprietary design technology to reduce power consumption, while maintaining high performance and low noise. The device is capable of up to 10 Million Samples Per Second (MSPS) and is capable of converting analog signals to digital signals within a frequency of 40 MHz.

The technology used for the design of the ADS7822UB is based on a successive approximation architecture and has been developed with the purpose of minimizing power consumption. The design also boasts a high-speed Schmitt-Trigger input which helps to reduce noise and enhance the accuracy and stability of the analog-to-digital conversion. The device also features auto power-down, allowing the device to power down when not in use, further conserving energy and reducing power consumption.

The range of applications the ADS7822UB can be used for is vast, however, it is most commonly used in applications that require high speed data acquisitions ranging from four to ten-bits of resolution. This includes applications such as medical, industrial and automotive testing, automotive or aircraft instrumentation and automated testing.

The ADS7822UB also has excellent electrical characteristics, including high-speed conversion while remaining low power and low noise. Cross-coupling interference and other changes to the input signal are greatly reduced by the Schmitt-trigger input and the conversion accuracy is such that it can easily detect signals which differ by as little as 30 μV. The device also features a low-voltage sensing mode which allows for the monitoring of very low voltage sources and signals.

The ADS7822UB is also capable of removing noise from the input signal and reducing the effects of crosstalk, enabling signals of varying frequencies to be converted with minimal noise interference. The device is also capable of over-range detection and has the ability to detect low-level signals, requiring a dynamic range of 44 dB.

The ADS7822UB is an excellent choice for applications that require high-speed, low-noise, high-resolution analog-to-digital conversion. The devices low power consumption and Schmitt-Trigger input make it ideal for applications in which energy and power conservation are a priority. The ADS7822UB is also capable of converting a wide range of frequencies, including very low and very high frequencies, allowing it to be used in a wide range of applications.
