Evaluation Boards - Analog to Digital Converters (ADCs)

The EVAL-AD7993EBZ is an evaluation board that allows users to test out and familiarize themselves with the AD7993 multiplexed 8-to-1 analog-to-digital converter (ADC). It’s an ideal solution for a variety of applications, many of which require precise analog-to-digital conversion of signals.

Application Field

This evaluation board is designed to help users understand and evaluate the features of the AD7993 ADC and see how it can be used in various applications. The EVAL-AD7993EBZ has been designed to be used for a wide variety of applications, such as telecommunication systems, process control systems, instrumentation, automotive and industrial systems, and medical devices. Due to its low power consumption and high resolution, it is ideal for use in battery-operated systems.

General Features

The EVAL-AD7993EBZ evaluation board is a complete development platform for testing the AD7993 ADC. It features a low-power, 8-bit ADC, up to 8 analog input channels, and an SPI-compatible digital interface for ease of communication. The board also includes test points, headers, and an onboard LED indicator to identify the status of the ADC.

Working Principle

The AD7993 chip is an 8-channel, low-power multiplexed analog-to-digital converter. It features an input signal range of Differential= ±2.5 Vin, Single-ended= 0V to 2.5V, and a sampling rate up to 10ksps for single-ended and 20ksps for differential inputs. The EVAL-AD7993EBZ includes a low-noise preamplifier and an adjustable reference voltage so that users can test different input voltage ranges, gain settings, and resolutions.Once the EVAL-AD7993EBZ has been set up with appropriate power, analog, and digital-to-analog connections, it is ready to be used. Users can configure the board for single-ended or differential input and select the channel that needs to be converted. They can also select the gain for the preamplifier and set the reference voltage to be used for the conversion.Once the configurations have been set, the user can provide the analog input signal to the selected channel, and the AD7993 chip will process the input signal and convert it into an 8-bit digital result. The digital result can then be acquired using the on-board SPI interface, and the user can then check the accuracy of the converted data and adjust the configurations accordingly.

Conclusion

The EVAL-AD7993EBZ is a versatile, low power ADC evaluation board that can be used for a wide variety of applications. It features a versatile input signal range, adjustable reference voltage, and a digital interface so users can quickly and easily test out different configurations for their applications. With its low power consumption and pre-tested board, it is ideal for battery-operated systems.
