With a highly integrated design and a wide variety of application fields and wide range of working principles, the EVAL-AD7984-PMDZ Evaluation Board is an ideal solution for system and peripheral designs, filtering and signal processing, data acquisition, industrial sensing, and more.

Application Field

The EVAL-AD7984-PMDZ Evaluation Board is ideally suited for applications such as system or peripheral design, filtering and signal processing, data acquisition, industrial sensing, and many more. The board’s 12-bit resolution and 5Msps data acquisition rate makes it suitable for a variety of applications including embedded systems, consumer devices, audio, automation, IoT, imaging, telecoms, sensing, and home and industrial automation.

The EVAL-AD7984-PMDZ Evaluation Board is easy to use and configure for a wide range of applications. With a flexible architecture, the board also has a 12-way Analog Multiplexer (MUX) and can support up to 4-channels simultaneous sampling. The board also offers a wide range of external programmable gain amplifiers (PGAs) to allow for the customization of processing of signals with different amplitudes ranging from 4S to 10 V/V. A two-way Serial Peripheral Interface (SPI) communication port allows for easy configuration and communication with external systems.

Working Principle

The EVAL-AD7984-PMDZ Evaluation Board takes advantage of the integrated 12-bit, 5Msps, 4-channel ADC coupled with external Programmable Gain Amplifier (PGA). This is combined with a two-channel Serial Peripheral Interface (SPI) communication port to allow for easy configuration and communication with external systems. Through the data capture board, signals from multiple sources can be received with excellent sensitivity and dynamic range while using a single ADC.

The working principle of the EVAL-AD7984-PMDZ Evaluation Board is based on the following sequence. First, the input signal is amplified by the external programmable gain amplifier (PGA). The amplified signal is connected to the board’s 12-way multiplexer (MUX) to ensure a maximum of 4 channels are simultaneously sampled. The multiplexer is then connected to the internal 12-bit ADC, where the data is digitized. The digitized data is sent over the two-channel SPI port to an external controller for further processing.

The EVAL-AD7984-PMDZ Evaluation Board also features a number of control options, including GPIOs, external clocks, and SPI communication ports to easily handle the analog-to-digital conversion process. Additionally, separate DC and AC power supplies are available on the board for use with a variety of devices. Finally, the board includes a number of safety features such as an over-voltage protection circuit and ESD protection.

Conclusion

With its integrated 12-bit, 5Msps, 4-channel ADC and external programmable gain amplifier (PGA), the EVAL-AD7984-PMDZ Evaluation Board is an ideal solution for system and peripheral designs, filtering and signal processing, data acquisition, industrial sensing, and much more. The highly integrated design and a wide range of application fields make the board extremely versatile and easy to use. Moreover, the board’s working principle allows it to take advantage of the internal ADC and multiplexer to efficiently capture data with excellent sensitivity and dynamic range. With all these features, the EVAL-AD7984-PMDZ Evaluation Board is a great choice for any designer looking to speed up the development of their application.
