Data Acquisition - Digital to Analog Converters (DAC)

Digital-to-analog converters (DACs) are electronic components which convert digital data into analog data. A variety of DACs exist by providing different levels of resolution and speed. The AD7391ARZ-REEL7 is a voltage-output, 8-bit DAC which is suitable for a wide range of applications.

Overview of the AD7391ARZ-REEL7

The AD7391ARZ-REEL7 is a voltage output, 8-bit digital to analog converter (DAC) offering superior linearity and accuracy at very low power consumption. It is available in a small 14 pin thin shrink small outline package making it suitable for space-constrained applications. The converter operates from a single 5V power supply but the reference input may operate from -10V to +10V offering a wide range of operation and performance.The model number indicates that it is a reeled package with 8 bit resolution and a rated output of 0-2.5V. It has a maximum power consumption of 150mW, a settling time (at 25°C) of 2µs and an operational temperature range of -40 to +85°C. The AD7391ARZ-REEL7 has an operating voltage range from 4.75V to 5.25V and an operating current of 13.5mA.

Features & Functions of the AD7391ARZ-REEL7

The AD7391ARZ-REEL7 features several functions to ensure superior linearity and accuracy at very low power consumption. It uses a wide input voltage range which allows for different conditions and applications. Excellent linearity and matching accuracy is achieved with an internal, buffered, segmented reference with 24.4mV resolution. The converter includes a three-wire serial interface with active-high chip select and a control bit for power-down and active-low reset functions. The output buffer of the converter offers excellent linearity and reduces droop. Additionally, the output buffer is designed to provide increased noise immunity and fast settling times. Finally, the AD7391ARZ-REEL7 is designed to be very easy to use with the availability of ready-made evaluation boards to help simplify the set up and testing of the circuitry.

Application Fields of the AD7391ARZ-REEL7

Due to its excellent performance parameters, the AD7391ARZ-REEL7 can be used in a wide range of applications. It is suitable for consumer, industrial, and military electronics applications where a voltage-output DAC with high accuracy and low power consumption is required. The AD7391ARZ-REEL7 is ideal for sensor calibration and analog interface applications such as industrial automation, process control, and medical systems. Furthermore, it is suitable for use in high accuracy data acquisition systems, instrumentation amplifiers, digital signal processing systems, and digital control systems. It is also suitable for use in medical imaging applications, radar and satellite systems, and digital filtering systems.

Working Principle of the AD7391ARZ-REEL7

The AD7391ARZ-REEL7 works by taking an input digital word which is then converted into its equivalent 8-bit or 16-bit analog voltage. The converter uses an internal DAC and a buffered reference to ensure the highest accuracy. The AD7391ARZ-REEL7 receives its digital words through a three-wire serial interface. The data is then converted to its equivalent analog voltage output by the internal DAC and reference. Finally, the output buffer of the converter is used to reduce droop and increase noise immunity. The output buffer also helps to improve settling time. The current output of the converter can be adjusted by the output buffer for different applications.
