The AD7482BSTZ is a 16-bit, 10-bit, 8-bit and 6-bit, low power, high speed, successive approximation analog-to-digital converter (ADC) with integrated track-and-hold amplifier. It is designed with hundreds of applications in mind, ranging from high speed data acquisition to color sensor data acquisition. This article will discuss the working principle and application field of the AD7482BSTZ.

Working principle

The AD7482BSTZ uses successive approximation register (SAR) architecture, which is powered by a proprietary low-latency switching technique that delivers very fast conversion. The process starts when a voltage signal is applied to the input of the ADC. A sample-and-hold amplifier is responsible for buffering the input signal, which is then stored in an internal register. A comparator then compares the stored voltage to the output of a digital-to-analog converter (DAC). If the stored voltage is greater than the DAC output, the next bit of the sequence is clear; if it is lower, the bit is set. This process is repeated for each bit of the data sequence, until the final result is obtained. The successive approximation process results in very fast conversion times of less than 10 µs.

Application field

The AD7482BSTZ is highly suitable for applications such as analog-to-digital converters (ADCs) and digital-to-analog converters (DACs). Its integrated track-and-hold amplifier helps to maximize system performance and accuracy by providing an accurate sample of the input signal. Its wide range of 10-, 16-, 8- and 6-bit resolution makes it a suitable choice for various types of applications, such as high speed data acquisition, color measurement, and medical imaging. Furthermore, its low power consumption, high input bandwidth, high sampling rate and high speed conversion make it a cost-effective choice for a wide range of applications.

The AD7482BSTZ can be used in a variety of applications, including data acquisition systems, industrial instrumentation, audio/video digitizers, medical imaging systems, and portable data acquisition and test systems. The wide range of available resolution and the fast conversion time make it an ideal choice for portable instruments that must capture data quickly and accurately. Furthermore, its low power consumption makes it suitable for battery powered equipment. Finally, its intrinsic noise immunity makes it suitable for use in noisy environments.

In conclusion, the AD7482BSTZ offers a wide range of features for applications requiring fast and accurate acquisition. Its integrated sample-and-hold amplifier, low power consumption, wide range resolutions, and fast conversion time make it an ideal choice for a variety of applications. It is suitable for use in data acquisition, industrial instrumentation, audio/video digitizers, medical imaging systems, and portable test systems.
