Evaluation and Demonstration Boards and Kits are pieces of electronic hardware, consisting of a printed circuit board or a daughterboard, used to evaluate the functionality of a device, module or system. TheEVAL-AD9984AEBZ evaluation board is a piece of hardware designed specifically to evaluate Analog Devices Inc.\'s AD9984A family of ultra-low power, low power dissipation programmable velocity-mode (PVM) voltage output ADCs.

Applications of EVAL-AD9984AEBZ

The uses of the EVAL-AD9984AEBZ are primarily for evaluation, testing and demonstration, but they can also be used to integrate multiple functions into a single system, design a new device or create a prototype. The board can be employed for a multitude of applications, including, but not limited to, automotive, medical, industrial and communications systems.

In automotive systems, the EVAL-AD9984AEBZ can be used for electric powertrain control, fuel and engine management, navigation and infotainment systems. For medical systems, the evaluation board can be used in hospital information systems, imaging, and patient monitoring. The board is suitable for industrial system measurement and control, precision automation and robotics. The board can also be used for mobile antenna tuning and air interface testing in communications systems.

Working Principle

The EVAL-AD9984AEBZ evaluation board is based on the AD9884A family of ultra-low power, low power dissipation programmable voltage output ADCs. The board contains a voltage reference, a gain-select resistor network, an op amp and a single-wire programmable analog-to-digital converter. The benefit of the single-wire programmable ADC is that it allows the user to switch gain levels with a single control command. This allows for flexibility in the system design and for multiple applications to be integrated into a single system.

The voltage reference provides a precision input voltage reference for the ADC that is temperature compensated. The gain-select resistor network consists of six sets of gain-select pins that allow the user to select a gain level of either 0.25 V/V, 0.50 V/V, 1.00 V/V, 2.00 V/V, 4.00 V/V and 8.00 V/V. The op amp is responsible for amplifying the signal and providing a desired topology of the output waveform. Finally, the ADC is responsible for converting the input signal into a digital signal.

Once the gain level is selected, the EVAL-AD9984AEBZ board is then used to evaluate the performance of the ADC. The board can be used to test the throughput speed, conversion accuracy, linearity, noise performance, power dissipation and signal to noise ratio of the board. The board also supports external programming, allowing the user to change the gain levels remotely.

Conclusion

The EVAL-AD9984AEBZ evaluation board is an incredibly useful tool for evaluation, testing and demonstration of AD9884A family of ultra-low power, low power dissipation programmable voltage output ADCs. This board can be used for a wide range of applications, including automotive, medical, industrial and communications systems. The board contains a voltage reference, a gain-select resistor network, an op amp and a single-wire programmable ADC, and it can be used to test a variety of parameters, such as throughput speed, conversion accuracy, linearity, noise performance, power dissipation and signal to noise ratio.
