EVAL-AD7192EBZ is an evaluation board that offers an 8-channel, high-resolution, low noise, analog-to-digital converter (ADC). Based on the AD7192EBZ, the evaluation board is designed to directly interface with a microcontroller or a field-programmable gate array (FPGA). With its low noise, this board is highly recommended for applications that require high resolution such as remote sensing, precision metering, motion control, and critical industrial automation.

The EVAL-AD7192EBZ features an integrated temperature sensor and remote temperature-sensing function. The integrated system temperature sensor enables temperature-compensated ADC conversions for applications demanding extreme accuracy. When the remote temperature-sensing function is enabled, it allows multiple remote nodes connected to the evaluation board to monitor temperatures of multiple locations. This is particularly useful in industrial automation applications where measuring of temperatures in multiple locations requires high accuracy.

The EVAL-AD7192EBZ includes an integrated watch-dog timer to protect against corruption of data due to power failure or noise. The timer equips the board with a fail-safe feature which activities a reset sequence when unexpected errors occur. The fail-safe circuitry can store data up to 8-bits to distinguish errors from input signals. The timer is also capable of detecting input signals and activate specific functionalities. This ensures data is reliably protected and reduces data processing time.

The analogue-to-digital conversion (ADC) architecture employed by the EVAL-AD7192EBZ uses a successive approximation register (SAR) method. This process is based on charging and discharging an internal tracking capacitor with the input voltage. The SAR logic cycles back-and-forth on the tracking capacitor until the voltage converges to the source input. In general, this SAR method provides higher conversion speed and superior linearity as compared to other conversion techniques.

The EVAL-AD7192EBZ supplies the necessary functionality for analog-to-digital conversion applications. Its superior performance and low noise properties allow for a wide range of applications, from precision metering to industrial automation. Its integral system temperature sensor and remote temperature-sensing functions enable precision temperature measurements and increased system accuracy. The on-board watch-dog timer provides a fail-safe mode which helps protect against power or signal failure or errors in data processing. Finally, the highly accurate SAR ADC provides a fast and reliable conversion of analog signals.
