Analog to Digital Converters (ADCs) have become increasingly important as electronic systems require more and more high speed data. As such, many companies are offering Evaluation Boards which are designed to allow users to quickly evaluate the performance of their products. The most advanced of these Evaluation Boards is the EVAL-AD7298SDZ, which offers excellent performance for a variety of applications, including those related to Data Acquisition, signal processing, and more. In this article, we will discuss the application field and working principle of the EVAL-AD7298SDZ.

The EVAL-AD7298SDZ is an Evaluation Board that provides the user with a complete Data Acquisition system. It is designed to evaluate the performance of the Analog Devices AD7298 12-bit, 1-Msps Sigma-Delta Analog-to-Digital Converter (ADC). This Evaluation Board is ideal for high-speed data conversion applications, such as ultrasound imaging, magnetic resonance imaging (MRI), medical instrumentation, and industrial process control. It features dynamic performance, low power consumption, high accuracy, and low noise.

The EVAL-AD7298SDZ Evaluation Board features an onboard 16-bit ARM Cortex-M4 processor which allows for direct control and data acquisition applications. It also provides multiple interface options such as SPI, I2C, and digital inputs/outputs. Furthermore, the board provides eight programmable gain amplifier (PGA) channels for optimal signal conditioning in various applications.

The EVAL-AD7298SDZ Evaluation Board also features an onboard temperature sensor and SPI peripheral block for SPI programmable temperature compensation. This enables precise and accurate data acquisition and signal processing in a wide variety of applications. Furthermore, the Evaluation Board also features an onboard FPGA with an integrated PWM controller, making it an ideal solution for power-sensitive applications.

The EVAL-AD7298SDZ Evaluation Board is powered by an externally regulated 3.3V power supply. It operates up to 3.3V IO operating conditions (VCCL-VCC – 0.8V). Additionally, the EVAL-AD7298SDZ contains several power supply electrical protection features such as short circuit protection and over-voltage protection.

In terms of its working principle, the EVAL-AD7298SDZ Evaluation Board enables a high degree of accuracy and signal resolution with a 12-bit, 1-Msps sigma-delta ADC. This ADC operates by continuously sampling an analog input signal, and then converting it into a digital form which is then sent to a digital processor. The onboard FPGA then processes the digital signal, which is then passed through an analog-to-digital converter to create a wideband analog output.

The EVAL-AD7298SDZ Evaluation Board is an ideal solution for a variety of application fields, such as medical instrumentation, industrial process control, aerospace and defense, and many others. It offers high accuracy, low power consumption, dynamic performance, and low noise. The onboard ARM processor and FPGA make it an ideal solution for direct control and data acquisition, while the onboard temperature sensor and SPI peripheral block provide accurate temperature compensation. All of these features make the EVAL-AD7298SDZ Evaluation Board a powerful and reliable solution for a variety of analog to digital conversion applications.
