Data acquisition is an important process in many applications, where the complex and dynamic nature of real-world phenomena needs to be represented as digital information by transducing and sampling physical information (analog signals). The conversion of analog signals representing physical information into digital data is accomplished with an analog-to-digital converter (ADC).AD7827BRZ-REEL7, manufactured by Analog Device, is an example of a data acquisition system. It is based on a delta-sigma converter, which is ideal for producing high-resolution digital data from low-voltage input. The system operates in a single-supply, low-power mode, making it useful in a variety of power-sensitive applications, such as portable and battery-powered devices.The AD7827BRZ-REEL7 system measures voltage and temperature with a differential input range of -2.5 to +2.5 V, and a programmable gain range of 1 to 8. It has an input capacitor, which allows a wide variety of alternative capacitor values to be programmed. The device contains a precision internal reference, which can be used to reduce the external component count.The AD7827BRZ-REEL7 system has a 10-bit resolution, and provides a wide range of output formats, including 8-bit unipolar (unsigned), 10-bit unipolar (unsigned) and 12-bit twos complement (signed). The device also provides a single-cycle power-on reset, as well as overtemperature, overvoltage and undervoltage protection features.The AD7827BRZ-REEL7 system is suitable for applications such as bridge sensor measurements (strain gauge, pressure sensor, flow meter, etc.), thermometry, medical equipment, industrial control, energy management and other low voltage, low power sensing applications.The operation of the AD7827BRZ-REEL7 system is based on a delta-sigma analog-to-digital conversion scheme. This scheme uses oversampling and noise shaping techniques to achieve high resolution from a low-resolution device. The delta-sigma process reduces jitter in the output, by taking the noise that is introduced by the analog-to-digital conversion process and shaping it into a higher frequency. This results in a cleaner signal with less noise, and thus allows the ADC to operate at a high sample rate, which is the key to high resolution.The AD7827BRZ-REEL7 system is a fast and accurate ADC and is suitable for a wide range of data acquisition applications. It operates in a single-supply, low-power mode, making it an ideal operating system for portable and battery-powered devices, as well as low-voltage sensing applications. The device contains a precision internal reference and provides output formats, including 8-bit unipolar, 10-bit unipolar and 12-bit twos complement, which makes it a versatile ADC suitable for a variety of applications.
