Data acquisition is the process of sampling signals that measure real world phenomena and converting those signals into digital numeric values that can be manipulated by a computer. Digital to analog converters (DACs) are the digital building blocks used to convert digital signals into analog signals for data acquisition. The AD7248ABNZ is one such DAC designed for use in data acquisition applications. This article will discuss the application field and working principle of the AD7248ABNZ.

Application Field

The AD7248ABNZ is a high speed, low power digital-to-analog converter with a Vin voltage range of ±1.7V to ±5.5V. It features on-board reference voltage and is capable of producing 12-bit resolution of up to 10MHz conversion rates. The converter also has a wide operating temperature range, making it suitable for both industrial and consumer applications.

The AD7248ABNZ is designed to be used in a wide range of data acquisition applications, including industrial process control, medical imaging, consumer electronics, and automotive systems. It is also well-suited to applications requiring high speed precision signal conversion and low power consumption. The AD7248ABNZ is especially well-suited for applications that require multiple-bit accuracy.

Working Principle

The working principle of the AD7248ABNZ is based on the principles of pulse-width modulation (PWM). A PWM signal is a type of digital signal in which the signal’s width is modulated in order to represent a desired analog voltage. PWM signals are used in a wide range of data acquisition applications, including digital-to-analog conversion.

The AD7248ABNZ takes a digital input signal and uses a PWM technique to modulate the signal in order to produce an analog output. The input signal is fed into a low-noise amplifier, which amplifies the signal and then passes it through a comparator. The comparator then produces a pulse-width modulated signal, which is then converted into an analog voltage.

The AD7248ABNZ also features several features that can improve its performance in different applications. For example, it features three selectable speed modes, allowing the user to adjust the converter’s sampling rate to match the requirements of the application. It also has a programmable output offset, allowing the user to adjust the output level of the converter to match the input signal. Additionally, the AD7248ABNZ features internal temperature monitoring, allowing the converter to make adjustments to its output level to compensate for variations in temperature.

Conclusion

The AD7248ABNZ is a versatile and high-performance digital-to-analog converter designed for use in a wide range of data acquisition applications. It is capable of producing 12-bit resolution of up to 10MHz conversion rates with a wide operating temperature range, making it suitable for a variety of industrial, consumer, and automotive applications. It works using a low-noise amplifier and a pulse-width modulation technique to modulate the input signal and produce an analog output. The AD7248ABNZ also features several features that can improve its performance, including selectable speed modes, programmable output offsets, and internal temperature monitoring. By understanding the application field and working principle of the AD7248ABNZ, users can easily identify the right DAC to meet their needs.
