EVAL-AD7683SDZ

Introduction

Evaluation Boards - Analog to Digital Converters (ADCs) have been a popular choice among users who employ advanced signal processing methods and require high throughput performance in order to achieve the best results. The EVAL-AD7683SDZ is an evaluation board designed for use with integrated circuit (IC) products that incorporate the MIXED-SIGNAL IC - AD7683. This evaluation board enables users to quickly evaluate the features of the device and test its performance.

EVAL-AD7683SDZ Application Field and Working Principle

The EVAL-AD7683SDZ evaluation board has a 16-bit, single-channel Analog-to-Digital Converter (ADC) at its core, making it suitable for applications such as signal processing, data acquisition, and instrumentation. In terms of its performance, the device can sample at a rate of up to 4MSPS over a range of input voltages from 0V to 5V. Additionally, the on-board S/H circuitry enables the device to sample signals with minimal noise.

Within the device\'s architecture, a differential input amplifier with a ± 1.0V common mode input range, low level offset voltages, followed by a 1st-order anti-aliasing filter are consituted. The digital output stage includes Delta Sigma modulator, a 16-bit digital filter, and a 16-bit DAC. The device also includes on-chip temperature compensation, reference buffering, and programmable clock dividers, which enables users to set up the desired sampling rate. All of these attributes make the EVAL-AD7683SDZ a great choice for applications that require high resolution and sampling rates.

Power Supply, Interface, and Pin Assignments

The power supply for the EVAL-AD7683SDZ board is single 3.3V DC power supply, which can be supplied either via the on-board 2.1mm barrel jack or via the terminations in the back panel. The SMA and BNC connectors in the back panel can be used for connecting to external reference signal and ground. Additionally, the board features a 16-bit double-buffered, serial peripheral interface (SPI) that enables the device to be programmed and configured with the use of an external controller.

The evaluation board includes 16 dedicated user accessible pins for connecting directly to the system-level components. These pins are grouped into analog, digital, power, and interface categories. The pin assignments for each group are as follows: The analog pins are dedicated to the input signal and reference; the 2 digital pins are for control data and clock transfer; the SMA and BNC connectors are used to connect external reference signals and grounds; and the 16-bit on-board SPI enables the device to be controlled from an external controller.

Conclusion

The EVAL-AD7683SDZ evaluation board is one of the most advanced in its class and is suitable for applications that require high throughput performance and require advanced signal processing. The board is powered by a single 3.3V DC power supply and features a 16-bit, single-channel ADC at its core, allowing it to sample at a rate of up to 4MSPS. Additionally, it features a 16-bit double-buffered, serial peripheral interface which enables the device to be programmed and configured via external controller and offers 16 dedicated user accessible pins for system-level connections. All of these features make the EVAL-AD7683SDZ a great choice for users who require high resolution and sampling rates.
