Analog-to-digital converters (ADCs) are essential to many modern electronic systems. They can be used to convert analog signals into digital signals for subsequent processing by a computer or other digital circuitry. The EVAL-AD7693CBZ is one such Analog-to-Digital Converter (ADC) designed to provide high-performance and accuracy.

The EVAL-AD7693CBZ board is a low-power, configurable application development board designed for intuitive evaluation of the AD7693 analog-to-digital converter. It measures the analog input voltage in the range of -0.3V to +3.3V, and is capable of providing a conversion rate of up to 500k samples per second. The board can also be configured for single or dual channel operation, providing flexibility in a range of applications.

In terms of application fields, the EVAL-AD7693CBZ can be employed in a number of fields from sensors to automotive monitoring and analysis of analog signals. Examples of these include medical monitoring systems, monitoring of industrial processes, or earthquake and seismic measurements.

At the core of the EVAL-AD7693CBZ is the AD7693 12-bit BiCMOS analog-to-digital converter. The converter combines low power and small size, yet provides a high resolution conversion with an ENOB of 10-bit at up to 500k samples per second. The core operates from a 0.9V to 1.8V (+/- 5%) voltage range.

The EVAL-AD7693CBZ operates on both single and dual channel configurations. In the single channel configuration, the EVAL-AD7693CBZ has an onboard 32 kB of SRAM, and SPI interface, and provides user-programmable gain and offset control. The dual channel configuration provides an additional 16 kB of SRAM, LTC2990 temperature sensor, and temperature compensation. The board uses a USB connectivity for programming and drivers, allowing easy configuration and debug.

The processing of the EVAL-AD7693CBZ can be further optimized using the onboard SupportManger software package. It is an integrated environment for evaluation and testing of AD7693, and provides support for setup, parameterization, and data logging. The user can select the target channel, gain, and offset, and then use the software to gain quick insight into the performance of the AD7693 converter.

In conclusion, the EVAL-AD7693CBZ is a versatile evaluation board for high accuracy analog-to-digital converter applications. It offers low power consumption, small size and high resolution with an ENOB of 10-bit up to 500k samples per second, and an onboard 32kB SRAM. Flexible programming and driver support via USB makes the board easy to configure and use. The SupportManger software package helps optimize the board performance, allowing users to quickly gain insight into the performance of the AD7693 converter.
