Analog-to-Digital Converters (ADCs) are components in the electronic world that convert analog signals into digital ones for further processing, computation, and analysis. When designing a system that requires ADC support, developers need to choose the ADC type that best fits their product’s requirements. EVAL-AD7988-5SDZ is an evaluation board that has been developed to help evaluate Analog Devices’ AD7988, a 8-/10-/12-bit precision sigma-delta ADC. It is capable of self-calibration and provides external input signals for temperature measurements. This evaluation board makes it easy to evaluate AD7988’s performance in various situations. By understanding the board’s features and functionality, developers can quickly assess the ADC’s potential to meet their needs.

Application Field and Working Principle

The EVAL-AD7988-5SDZ evaluation board supports the Analog Devices’ AD7988 8-/10-/12-bit precision sigma-delta ADC. This board provides access to the core of the AD7988, allowing engineers to evaluate the performance of the device in their own systems. The AD7988 can be used to process analog signals for such applications as data acquisition, signal conditioning, and automation systems. In addition, the board is suitable for temperature sensors and signal diagnostics.

This evaluation board features a robust on-board circuit for powering the AD7988. It includes a low-dropout regulator, switchable reference, and temperature sensor. This combination provides reliable, high-accuracy supply voltages and temperatures for the device. The evaluation board also includes several external interface options to facilitate easy connection to other components and systems.

The AD7988 can measure small voltage differences in a wide range of input signals, and it has efficient signal-to-noise ratio for signal processing. To simplify the evaluation process, the board offers differential and single-ended input signals for the ADC. The input signals are buffered and amplified before reaching the actual AD7988 to ensure accuracy and signal integrity. Additionally, the on-board potentiometer allows manual adjustment of the input reference voltage.

The AD7988 is functionally capable of providing 8-, 10-, and 12-bit sampling accuracy. The board provides two output option: TTL (transistor-transistor logic), which is the digital representation of the conversion result and PWM (pulse width modulation). With the PWM output, users can get a digital representation of the result, with an accurate duty cycle indicating the digital output result.

The onboard temperature sensor allows engineers to measure the conversion results in temperature terms. By connecting the board’s temperature sensor to an external thermocouple, such as a K-type thermocouple, the board can accurately measure temperatures up to 600 °C. This feature is particularly useful in applications involving harsh environment temperatures, such as automotive and industrial.

Because the AD7988’s evaluation board supports the AD7988’s self-calibration features, it can be used to accurately measure small and ac signals with low distortion and low noise. Finally, the board can be used in applications that require high-dynamic range, such as audio and medical imaging.

All in all, the EVAL-AD7988-5SDZ evaluation board provides engineers with a powerful tool to evaluate the ADC’s performance for various applications. By providing an easy-to-use, feature-rich environment, the evaluation board reduces the time needed for system development and manufacturing.
