Evaluation Boards - Analog to Digital Converters (ADCs) can be applied in a range of different areas, including, but not limited to control systems, telecommunications, automotive, medical, and consumer electronics. ADC boards are designed to measure and convert analog signals into digital signals, and the DQC1190A-C Evaluation Board is no exception. This board provides an easy way to evaluate the performance of the delta-sigma ADCs from Tektronix (DSA9805S and DSA9901S). This article will provide an overview of the DQC1190A-C Evaluation Board’s application fields and its working principle.

The DQC1190A-C Evaluation Board is focused on the evaluation of the performance of Tektronix’s delta-sigma ADCs. It is an all-in-one hardware solution that includes a daughter board with the delta-sigma ADCs, a calibration system, communication interfaces for data download, signal generation components, and a control GUI. It provides all the necessary resources for engineers to configure and monitor multiple devices, verify the performance characteristics of the ADCs, and characterize the results. The GUI is a browser-based user interface that allows users to set up a wide variety of parameters. The boards also include an audio loopback connector that provides a simple path for evaluating the analog interface characteristics. The two Tektronix delta-sigma ADCs on the board are capable of measuring signals up to 75 dB SNR and 0.3% integral nonlinearity (INL).

The DQC1190A-C Evaluation Board is designed to provide engineers with an easy way to evaluate the performance of Tektronix’s delta-sigma ADCs. It can be used in a variety of application fields including audio, telecom, automotive, industrial control, medical imaging, and consumer electronics. For audio applications, the board is capable of accurately measuring and digitizing complex audio signals with low noise and high dynamic range. For telecommunications applications, the board can be used to evaluate the performance of analog-to-digital data converters in a variety of communication systems such as TDM/PCM or wireless telecommunication systems. For automotive applications, the board can be used to evaluate the performance of ADCs in power train and engine control systems. For industrial control, the board can be used to evaluate the performance of ADCs in medical imaging, autonomous vehicle control, and robotic arm control systems. Finally, for consumer electronics applications, the board can be used to evaluate the performance of ADCs in home entertainment systems.

The working principle of the DQC1190A-C Evaluation board is based on the delta-sigma architecture. A delta-sigma ADC is a type of analog-to-digital converter that uses a “analog-to-digital” or “digital-to-analog” method for converting an analog signal’s continuously varying amplitude into digital values. In a delta-sigma ADC, an analog signal is first sampled at a high frequency, and the sampled signal is then converted into digital data using a “delta-sigma” modulator. The delta-sigma modulator works by measuring the difference between the input signal and a reference level, and encoding the resulting digital signal with pulse width modulation (PWM) or pulse-density modulation (PDM). The output of the delta-sigma modulator is then filtered, or decimated, to obtain the final digital values of the signal.

In summary, the DQC1190A-C Evaluation Board is an all-in-one hardware solution that provides an easy way to evaluate the performance of Tektronix’s delta-sigma ADCs. It is designed to provide engineers with an easy way to configure and monitor multiple devices, verify the performance characteristics of the ADCs, and characterize the results. The board’s working principle is based on the delta-sigma architecture and it can be used in a variety of application fields including audio, telecom, automotive, industrial control, medical imaging, and consumer electronics.
