Data Acquisition - Analog to Digital Converters (ADC) includes a variety of technologies used to convert analog signals into a digital representation. One of the most popular and widely used ADC technology is the AD676KD. This device is an integrated application-specific high accuracy, low power, 24-bit, sampling delta-sigma ADC. This component offers several features, such as wide bandwidth and high linearity, which make it suitable for a variety of applications.

The AD676KD application field is focused on the Analog to Digital Conversion of very low power signals, such as those found in portable instrumentation and isolated industrial sensor applications. It is also used in medical data acquisition systems, where the application requires accuracy and low power for long operation hours. Additionally, the AD676KD is often found in automotive systems, including the CAN (Controller Area Network), where a low noise, high precision ADC is needed.

The working principle of the AD676KD is based on the classical delta-sigma converter architecture. The input signal is analyzed and compared to a voltage reference by the converter’s comparator in order to produce a digital output code. This code is then transmitted to a digital signal processor, where it is converted into the desired output. The AD676KD is capable of operating with a broad range of analog input levels, helping minimize signal distortion.

The main features of the AD676KD are its high linearity and wide dynamic range, which make the converter suitable for signal conditioning, filtering and precision measurements. Thanks to its low power design, the AD676KD is capable of running from a single supply, making it ideal for portable and battery-powered applications. The device also has an optimized low noise power supply which keeps power consumption low and makes it suitable for energy saving applications. Additionally, the AD676KD supports both single-ended and differential analog inputs, allowing users to choose the best possible configuration for their application.

The AD676KD is highly reliable thanks to its digital calibration technique, which eliminates temperature and supply drift. This reduces noises and make the converter suitable for 24-bit precision measurements. Its high precision allows users to measure very low signals without any additional noise. Furthermore, the AD676KD is ideal for low power applications thanks to its power down mode which allows the converter to enter a very low power standby mode that further reduces noise levels.

In conclusion, the AD676KD is an integrated 24-bit, low noise, low power ADC designed for Analog to Digital Conversion of very low power signals. With its wide bandwidth, high linearity and low power design, the AD676KD is well suited for a variety of applications, including portable instrumentation, data acquisition systems and automotive systems. Additionally, the device offers excellent error correction, low noise power supply and digital calibration for reliable and accurate measurements. Finally, its optimized low power design makes the AD676KD ideal for energy saving applications.
