Data Acquisition – Analog to Digital Converters (ADC) applies technology to capture data from the analog world, convert it to digital form, and then use the digital information for further processing. ADC is essential in converting analog signals into digital signals, as all data processing is carried out in the digital domain. The ADS4146IRGZT is a high-performance 14-bit ADC, offering real-time sampling up to 1000 kSPS and a wide input range.

Application Field

The ADS4146IRGZT ADC is suitable for wide range of data acquisition applications, including measuring instrumentation, industrial automation, medical, automotive, aerospace and military systems. The ADC can also be used in applications such as energy meters and telemetry where it is necessary to monitor and analyze signals in real-time. Additionally, the low power consumption of the ADS4146IRGZT makes it an attractive solution for many battery powered applications, such as medical and handheld devices.

Working Principle

The ADS4146IRGZT ADC works by first converting an analog signal into a digital signal. It does this by sampling the input signal at successive intervals, converting each sample into a digital form, and then using binary codes to represent the magnitude of the analog signal. The ADC is able to measure a wide input range by using multiple isothermal converters, each handling a different range of input signals. The ADC achieves high accuracy and resolution by using a delta-sigma modulator and a two-step AD conversion algorithm.

The delta-sigma modulator is an important part of the process as it allows the ADC to achieve wide dynamic range. The modulator works by converting an analog signal into a high-frequency digital signal which is then divided into several digital codes. The output of the ADC is the average of the codes generated by the delta-sigma modulator. The two-step AD conversion algorithm is used to further improve the resolution, accuracy and dynamic range of the ADC.

The ADS4146IRGZT is a highly integrated ADC that provides excellent performance, low power consumption and small size. The ADC has the ability to sample analog signals at very high speeds, which makes it suitable for demanding data acquisition applications. It is an ideal solution for many automotive, industrial and medical applications, where data acquisition and analysis needs to be carried out in real-time.
