Data Acquisition - Analog to Digital Converters (ADC)

The AD7472BR-REEL7 is an application field and working principle of Analog-to-Digital Converters (ADC). ADCs are an important type of Data Acquisition device that allow for the conversion of analog signals into digital data points.

Application Field of the AD7472BR-REEL7

The AD7472BR-REEL7 is a low-power, single-channel ADC that is designed for use in emerging portable and battery-powered applications. It has a wide operating range of 2.7V to 5.5V, a single-ended analog input, and a sampling rate of 10 MSPS (1Msps per channel). It is ideally suited for applications such as monitoring energy and temperature readings in battery-powered systems, and is also compatible with industry standard SPI and I2C protocols.

Features of the AD7472BR-REEL7

The AD7472BR-REEL7 features a low power operation, which makes it an ideal solution for portable and battery-powered applications. It has an 8-bit resolution, allowing for significantly improved precision over traditional 10-bit ADCs. It also has a relatively high sampling rate of 10MSPS (1Msps per channel). Additionally, it is also highly efficient, with a tiny 35µA maximum power dissipated. In addition to its low power operation, the AD7472BR-REEL7 features a very low power standby mode, with a maximum standby power draw of only 10µA.

Working Principle of the AD7472BR-REEL7

The AD7472BR-REEL7’s working principle is based on Sigma-Delta technology. This means that the device is able to convert incoming signals into digital data points, by taking multiple samples of the signal and then averaging them. This technology allows for improved accuracy, as the multiple samples allow for an accurate overall result. Additionally, this process also runs in a loop, meaning that the device is always ready to take readings when needed.

Furthermore, the AD7472BR-REEL7 also utilizes an integrated Programmable Gain Amplifier (PGA). This allows users to adjust the gain across the input range, allowing for greater accuracy in a wide range of signals. For example, this can allow for accurate readings when measuring both low and high voltages.

Overall, the AD7472BR-REEL7 is an effective ADC, designed specifically for the operation requirements of battery-powered and portable applications. Its low-power operation, low power standby mode, and high accuracy are all ideally suited for these types of applications. Additionally, its PGA allows for accurate readings for a wide range of signals.
