Data Acquisition - Analog to Digital Converters (ADC) is a field of technology dealing with the conversion of analog signals into digital signals. In this field, the AD7914BRUZ is an innovative product targeting high standard data acquisition. This is one of Analog Devices’ most balanced product designs to date, which offers reliable performance and incredible accuracy.

The operating principle of the AD7914BRUZ is based on a successive approximation register (SAR) technology. This means the part is designed to measure the difference between an input signal and a reference signal. This signal is then used to move the SAR through a complete conversion cycle, ending with data output of the approximate digital value of the input signal.

The AD7914BRUZ features low power consumption, high sampling rate and A/D resolution all in one tiny package. It contains an analog input referenced to an internal voltage reference, a sampling switch and the SAR converter. The part also includes an adjustable amplifier connected between the optional external reference voltage and the input voltage. This amplifying stage allows the converter to increase its accuracy. The A/D converter can be used with a wide range of input voltages - from 0.4V to 4V.

A low power auto-zero comparator helps maintain the proper input/output difference, while an auto-clamp feature minimizes distortion. The digital output of the A/D converter is programmed with 8 bits of resolution. The part has a throughput rate of 250ksps with a wide range of gain and dynamic performance. The design is extremely versatile and can be adapted to different applications with some external gain and filtering elements.

As with all Analog Devices’ products, the AD7914BRUZ is designed to provide reliable performance and an optimal solution for many data acquisition applications. It is a highly integrated and compact device ideal for applications where a low power solution is required. This includes test and measurement equipment, instrumentation systems and process control equipment.

The AD7914BRUZ is a high performance A/D converter that provides reliable accuracy while still remaining low power. The integrated design ensures that the design is well suited for data acquisition applications. With its low power consumption, high sampling rate, A/D resolution, and adjustable amplifier, it is an ideal solution for many applications.
