Data acquisition is an important activity in many disciplines, ranging from engineering and physics to biology and medicine. Converters are a key component of data acquisition systems, translating between digital and analog voltage levels. The AD7834ARZ-REEL is a single 8-bit voltage output DAC that can transfer digital code information into an analog voltage level. This application note will discuss the features and operation of the AD7834ARZ-REEL, as well as its typical areas of application.

AD7834ARZ-REEL Features and Principle of Operation

The AD7834ARZ-REEL is an 8-bit voltage output DAC that has been designed for use in data acquisition systems. It is designed to interface with A/D converters and D/A converters, and can provide an analog voltage level from a digital code. The AD7834ARZ-REEL has an effective voltage range from +2.5 V to +10.0 V, and output values can be set in 1 mV steps. Additionally, the device features low power consumption, fast settling time, and low EMI/RFI emissions.

The AD7834ARZ-REEL works by taking a digital code and converting it into an analog voltage. The DAC\'s resolution is determined by the number of bits that the digital code is composed of; the AD7834ARZ-REEL is an 8-bit device, which means that it has 256 possible discrete voltage output levels. The conversion process is performed by an 8-bit serial-input shift register, which is clocked into successive stages in order to generate the output voltage.
