Data Acquisition is a process for obtaining data from various physical entities. Digital to Analog Converters (DAC) are an important process in data acquisition and are often used in a variety of applications. The AD7945ARSZ-BREEL is a DAC integrated circuit (IC) which is widely used in a variety of data acquisition applications.

Application Field

The AD7945ARSZ-BREEL is a high performance DAC with 4-channel, 16-bit resolution which is ideal for medical imaging applications. It is used in medical ultrasound and Magnetic Resonance Imaging (MRI) systems, providing high quality digital signals with excellent linearity and noise rejection. Other application areas include analog-to-digital conversion, digital audio/video conversion, instrumentation, IR systems, and home theater equipment.

The AD7945ARSZ-BREEL is also used for industrial and automotive applications, providing a wide range of industrial and automotive sensors with the highest accuracy and precision. It can be used for temperature, pressure, strain, and motion control applications, as well as in energy management systems, power conversion systems, and security systems.

Working Principle

The AD7945ARSZ-BREEL is an analog-to-digital converter, which converts analog input signals into digital output signals. The device operates at a maximum resolution of 16-bits and includes 4-channels, allowing multiple input signals to be converted simultaneously. The converter uses a non-linearity correction technique to ensure accuracy and linearity of the output signals.

The device features a high-performance Delta-Sigma modulator, which uses a pulse-width modulation technique to convert the analog input signal into a digital output signal. The modulated signal is then routed through a low-pass filter to remove any unwanted high frequency components. The device also includes an internal bandgap reference, which provides a stable reference voltage for the analog input signal.

The AD7945ARSZ-BREEL is also equipped with built-in data Handling and control logic, which provides various features such as input and output data buffering, error detection and correction, power management, and more. The device also supports the Serial Peripheral Interface (SPI) for easy connection with a microcontroller.

The AD7945ARSZ-BREEL is an excellent choice for many data acquisition applications due to its high-performance, reliable operation, and wide range of features. Its high precision and linearity makes it suitable for medical imaging and other applications, while its low power consumption and wide temperature range make it suitable for industrial and automotive applications.
