DC981A/B

Evaluation and Demonstration Boards and Kits

The DC981A/B is an evaluation and demonstration board designed specifically for the evaluation of low power precision data converters. It contains three sections, each of which provides an efficient and convenient data converter evaluation environment arranged with a range of accessory components and an oscilloscope that can be used to evaluate characteristics such as power efficiency, dynamic performance and accuracy. The board is designed to be connected to the evaluation board and the necessary power supplies needed for data converter testing.

DC981A/B Application Field

The DC981A/B provides a comprehensive data converter calibration and evaluation environment, allowing users to get the evaluation result they need quickly and accurately. It can be used to evaluate the performance of a variety of data converters, including analog-to-digital (A/D), digital-to-analog (D/A) converters, and their derivatives such as cyclicRedundancy Check (CRC) converters, delta-sigma modulators, and digital up/down converters. It can help circuit designers accurately and quickly assess the dynamic performances of precision data converters. Additionally, designers can use the board to rapidly evaluate the power efficiency of data converters, and important performance parameters like settling time, power supply rejection ratio, signal-to-noise ratio, and THD.

DC981A/B Working Principle

The DC981A/B utilizes a variation on the traditional conversion process that requires three stages. First, a converter chip is powered by an integrated power management module, which is responsible for providing the required power level to the chip. The achievable power efficiency or power consumption of the converted data depends on this stage. The second stage consists of a range of passive components, such as the input filter, which are responsible for providing the MCU with the required signal levels to match the converter’s input range. The third stage is the actual conversion, during which the converter chip performs the required conversion task and sends the result back to the MCU.

The DC981A/B provides users with the necessary components and power supplies to interface with the converter chip, and it is designed to guarantee compatibility with a range of hardware configurations. The board also provides access to various tools to aid users in their evaluations. These tools include the oscilloscope, which allows designers to precisely monitor the waveform of the input signal and the conversion output, as well as an FFT analyzer that allows them to measure the signal-to-noise ratio and total harmonic distortion of the signal. Additionally, the board allows access to converters’ calibration and operational parameters.

Conclusion

The DC981A/B evaluation and demonstration board provides a comprehensive set of accessories and tools that allow designers to evaluate a wide range of data converters in a convenient and efficient manner. The board allows designers to measure a wide range of parameters, such as power efficiency, dynamic performance and accuracy. Furthermore, the board is easy to use and does not require deep knowledge of the intricacies of data converter operation, allowing designers to make quick changes to evaluation setups and get accurate results quickly.
