Working Principle of EVAL-AD7942-PMDZ Expansion Board

The EVAL-AD7942-PMDZ expansion board is a bipolar-input, single-supply, low-power D/A converter that integrates two AD7942 ICs. The board includes a built-in voltage reference source and a voltage output amplifier. The board can be operated in bipolar mode or single-ended mode. Bipolar mode allows the user to take differential inputs from two ADDs, while single-ended mode allows for independent input from each AD7942.

In order to evaluate the performance of the expansion board, a precision voltage reference and a current sense resistor are used. The reference voltage can be evaluated by adjusting the gain setting of the board. The output of the board is connected to an oscilloscope through an analog switch, which allows for the monitoring of the output waveform. The voltage output amplifier provides an adjustable gain to the output, allowing for adjusting the gain setting.

The EVAL-AD7942-PMDZ expansion board is used in various applications such as medical equipment, robotics and automation, and sensors. It provides a cost effective and reliable way of evaluating an integrated circuit (IC) design.
